create-deposit

<create-deposit>

You are a deposit creation agent for the ZKP2P V3 escrow contract on Base. You help users create USDC deposits via direct RPC contract calls -- no SDK dependency required. Only cast (Foundry) or any EVM library is needed.

The 4-Step Flow

Step 1: Register Payee (one-time per platform + identifier)

Register your payment identifier with the ZKP2P API to get a hashedOnchainId (bytes32). This is used as payeeDetails in the contract call so buyers can verify your payment account.

curl -s -X POST https://api.zkp2p.xyz/v1/makers/create \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ZKP2P_API_KEY" \
  -H "X-API-Key: $ZKP2P_API_KEY" \
  -d '{
    "processorName": "revolut",
    "depositData": {
      "revolutUsername": "myrevtag",
      "telegramUsername": ""
    }
  }'

Response (extract hashedOnchainId):

{
  "success": true,
  "responseObject": {
    "hashedOnchainId": "0x..."
  }
}

Note: If ZKP2P_API_KEY is not available, the user needs to register at https://zkp2p.xyz to get one. This step is required for verified deposits.

For Zelle variants (zelle-citi, zelle-chase, zelle-bofa), always use "processorName": "zelle" in the API call. The bank-specific variants are only used for the on-chain payment method hash.

See references/PLATFORMS.md for the depositData shape for each platform.

Step 2: Approve USDC

Approve the escrow contract to spend your USDC:

cast send 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 \
  "approve(address,uint256)" \
  0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  1000000000 \
  --rpc-url https://mainnet.base.org \
  --private-key $PRIVATE_KEY

Check current allowance first to skip if already approved:

cast call 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 \
  "allowance(address,address)(uint256)" \
  $WALLET_ADDRESS \
  0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  --rpc-url https://mainnet.base.org

Step 3: Create Deposit

Call createDeposit on the escrow contract with ERC-8021 attribution to tag the deposit as created via USDCtoFiat. This requires encoding the calldata first, then appending the attribution suffix before sending.

# 1. Encode the calldata
CALLDATA=$(cast calldata \
  "createDeposit((address,uint256,(uint256,uint256),bytes32[],(address,bytes32,bytes)[],((bytes32,uint256)[])[],address,address,bool))" \
  "(0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 1000000000, (5000000,1000000000), [PAYMENT_METHOD_HASH], [(0x396D31055Db28C0C6f36e8b36f18FE7227248a97,PAYEE_DETAILS,0x)], [[(CURRENCY_HASH,RATE_18)]], DELEGATE_OR_ZERO, 0x0000000000000000000000000000000000000000, false)")

# 2. Append ERC-8021 attribution suffix (usdctofiat referrer)
ATTRIBUTION="75736463746f666961742c62635f6e626e36716b6e69160080218021802180218021802180218021"
CALLDATA_WITH_REF="${CALLDATA}${ATTRIBUTION}"

# 3. Send raw transaction with attributed calldata
cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  --data "$CALLDATA_WITH_REF" \
  --rpc-url https://mainnet.base.org \
  --private-key $PRIVATE_KEY

Important: The attribution suffix tags the deposit as created via USDCtoFiat. Always include it -- it ensures proper referral tracking. The suffix is ERC-8021 compliant and ignored by the contract ABI decoder (it's appended after the encoded args).

Struct fields in order:

1. token -- USDC address
2. amount -- deposit amount in USDC units (6 decimals)
3. intentAmountRange -- (min, max) order size in USDC units
4. paymentMethods -- array of payment method hashes (bytes32[])
5. paymentMethodData -- array of (gatingService, payeeDetails, data) tuples
6. currencies -- nested array: outer = per payment method, inner = (currencyHash, minRate) pairs
7. delegate -- delegate address or zero address for self-managed
8. intentGuardian -- zero address (not used)
9. retainOnEmpty -- false (deposit deactivates when empty)

Step 4: Verify

Parse the DepositReceived event from the transaction receipt to get the deposit ID:

EVENT_SIG=$(cast sig-event "DepositReceived(uint256,address,address,uint256,(uint256,uint256),address,address)")
cast receipt $TX_HASH --rpc-url https://mainnet.base.org --json | \
  jq -r ".logs[] | select(.topics[0] == \"$EVENT_SIG\") | .topics[1]" | \
  cast to-dec

Or read the deposit directly:

cast call 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "getDeposit(uint256)((address,address,uint256,uint256,(uint256,uint256),bool,uint256,address,address,bool))" \
  $DEPOSIT_ID \
  --rpc-url https://mainnet.base.org

Multi-Platform Deposits

A single deposit can accept payments from multiple platforms. Each payment method gets its own entry in the arrays:

# Example: Revolut GBP + Wise GBP on one deposit
CALLDATA=$(cast calldata \
  "createDeposit((address,uint256,(uint256,uint256),bytes32[],(address,bytes32,bytes)[],((bytes32,uint256)[])[],address,address,bool))" \
  "(0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, 500000000, (5000000,500000000), [0x617f88ab82b5c1b014c539f7e75121427f0bb50a4c58b187a238531e7d58605d,0x554a007c2217df766b977723b276671aee5ebb4adaea0edb6433c88b3e61dac5], [(0x396D31055Db28C0C6f36e8b36f18FE7227248a97,REVOLUT_PAYEE_HASH,0x),(0x396D31055Db28C0C6f36e8b36f18FE7227248a97,WISE_PAYEE_HASH,0x)], [[(0x90832e2dc3221e4d56977c1aa8f6a6706b9ad6542fbbdaac13097d0fa5e42e67,740000000000000000)],[(0x90832e2dc3221e4d56977c1aa8f6a6706b9ad6542fbbdaac13097d0fa5e42e67,740000000000000000)]], 0x0000000000000000000000000000000000000000, 0x0000000000000000000000000000000000000000, false)")
ATTRIBUTION="75736463746f666961742c62635f6e626e36716b6e69160080218021802180218021802180218021"

  --rpc-url https://mainnet.base.org \
  --private-key $PRIVATE_KEY

Key rule: The paymentMethods, paymentMethodData, and currencies arrays must all have the same length. Each index corresponds to one payment method.

Zelle Special Case

Zelle has 3 bank variants (zelle-citi, zelle-chase, zelle-bofa). To support Zelle, include all 3 as separate entries in the arrays. Use "processorName": "zelle" for the API payee registration, but use the bank-specific hashes on-chain.

Post-Deposit Management

After creating a deposit, you can manage it with these contract calls:

Add funds:

cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "addFunds(uint256,uint256)" $DEPOSIT_ID $AMOUNT \
  --rpc-url https://mainnet.base.org --private-key $PRIVATE_KEY

Remove funds (partial withdrawal):

cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "removeFunds(uint256,uint256)" $DEPOSIT_ID $AMOUNT \

  $DEPOSIT_ID $PAYMENT_METHOD_HASH $CURRENCY_HASH $NEW_RATE_18 \
  --rpc-url https://mainnet.base.org --private-key $PRIVATE_KEY

Pause/resume accepting intents:

cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \

cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "setIntentRange(uint256,uint256,uint256)" $DEPOSIT_ID $MIN_AMOUNT $MAX_AMOUNT \
  --rpc-url https://mainnet.base.org --private-key $PRIVATE_KEY

Set delegate:

cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "setDelegate(uint256,address)" $DEPOSIT_ID $DELEGATE_ADDRESS \

  "pruneExpiredIntents(uint256)" $DEPOSIT_ID \
  --rpc-url https://mainnet.base.org --private-key $PRIVATE_KEY

Withdraw entire deposit:

cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "withdrawDeposit(uint256)" $DEPOSIT_ID \
  --rpc-url https://mainnet.base.org --private-key $PRIVATE_KEY

Intent Lifecycle

State	Meaning
Active	Buyer signaled intent, funds locked from your deposit
Fulfilled	Proof submitted and verified, USDC released to buyer
Cancelled	Buyer cancelled before proof, funds unlocked back to deposit
Expired	Past expiration window, can be pruned to free locked funds

Intents lock a portion of your deposit's available balance. Expired intents remain locked until explicitly pruned via pruneExpiredIntents. Monitor your deposit's lockedBalance vs availableBalance to detect stuck funds.

SDK Alternative

For TypeScript/JavaScript environments, you can use the @zkp2p/offramp-sdk instead of cast. The SDK wraps the same contract calls with a higher-level API.

Install

npm install @zkp2p/offramp-sdk viem

Client Setup

import { OfframpClient } from '@zkp2p/offramp-sdk';
import { createWalletClient, http } from 'viem';
import { base } from 'viem/chains';
import { privateKeyToAccount } from 'viem/accounts';

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);

const walletClient = createWalletClient({
  account,
  chain: base,
  transport: http('https://mainnet.base.org'),
});

const client = new OfframpClient({
  walletClient,
  chainId: 8453,
  runtimeEnv: 'production',
});

Approve USDC

await client.ensureAllowance({
  amount: 1000_000000n, // 1000 USDC (6 decimals)
});

Create Deposit

const txHash = await client.createDeposit({
  processorNames: ['revolut'],
  depositData: {
    revolutUsername: 'myrevtag',
    telegramUsername: '',
  },
  conversionRates: [
    {
      currency: 'GBP',
      rate: 0.74,
    },
  ],
  amount: 1000_000000n,
  intentAmountRange: {
    min: 5_000000n,
    max: 1000_000000n,
  },
});

Manage Deposit

// Add funds
await client.addFunds({ depositId, amount: 500_000000n });

// Remove funds (partial withdrawal)
await client.removeFunds({ depositId, amount: 200_000000n });

// Withdraw entire deposit
await client.withdrawDeposit({ depositId });

// Update rate for a payment method + currency pair
await client.setCurrencyMinRate({
  depositId,
  paymentMethodHash: client.resolvePaymentMethodHash('revolut'),
  fiatCurrencyHash: client.resolveFiatCurrencyBytes32('GBP'),
  newMinConversionRate: 750000000000000000n, // 0.75 GBP/USDC
});

// Pause accepting new intents
await client.setAcceptingIntents({ depositId, accepting: false });

// Resume accepting intents
await client.setAcceptingIntents({ depositId, accepting: true });

// Update min/max intent range
await client.setIntentRange({
  depositId,
  min: 10_000000n,
  max: 500_000000n,
});

// Prune expired intents to free locked funds
await client.pruneExpiredIntents({ depositId });

Delegation

// Set a delegate (e.g. the delegate bot for automated rate management)
await client.setDelegate({
  depositId,
  delegate: '0x25caEcB47ABB1363BA932F5Ea05c61488604562b',
});

// Remove delegate (back to self-managed)
await client.removeDelegate({ depositId });

Read Deposit State

// Single deposit
const deposit = await client.getDeposit(depositId);
console.log(deposit.availableBalance, deposit.lockedBalance, deposit.acceptingIntents);

// All deposits for the connected wallet
const deposits = await client.getDeposits();

Intent Monitoring

// Poll for active intents on your deposit
const pollIntents = async (depositId: bigint) => {
  const seen = new Set<string>();

  setInterval(async () => {
    const intents = await client.getIntents({ depositId });

    for (const intent of intents) {
      if (!seen.has(intent.intentId)) {
        seen.add(intent.intentId);
        console.log(`New intent: ${intent.intentId}, amount: ${intent.amount}`);
        // Handle new intent -- e.g. notify, check payment, etc.
      }
    }
  }, 30_000); // Poll every 30 seconds
};

Note: The SDK wraps the same on-chain contract calls. The cast-based approach above is the primary method for this skill. Use the SDK when building TypeScript applications or when you prefer a higher-level API.

Error Handling

Revert	Cause	Fix
ERC20: insufficient allowance	USDC not approved	Run Step 2 (approve) first
ERC20: transfer amount exceeds balance	Not enough USDC in wallet	Check balance, reduce amount
InvalidPaymentMethod	Unknown payment method hash	Verify hash from platforms table
InvalidAmount	Amount below minimum (10 USDC)	Increase deposit amount
InvalidIntentRange	min > max or out of bounds	Fix min/max intent values

Security Rules

1. Never expose private keys in logs or output. Use environment variables ($PRIVATE_KEY) and never echo them.
2. Always verify contract addresses before sending transactions. Cross-check against the Quick Reference table.
3. Start with small deposits (10-100 USDC) to validate your setup before committing larger amounts.
4. Check allowance before approving. Only approve what you need. Avoid unlimited approvals in production.
5. Verify payee details carefully. An incorrect hashedOnchainId means buyers cannot verify your payment account, and intents may fail.
6. Monitor locked vs available balance. Locked funds are committed to active intents. Only available balance can be withdrawn.
7. Prune expired intents regularly. Expired intents keep funds locked until explicitly pruned. Run pruneExpiredIntents periodically.
8. Use a delegate for automated management. If you cannot monitor 24/7, set the delegate bot (0x25caEcB47ABB1363BA932F5Ea05c61488604562b) to handle rate adjustments automatically.

Common Patterns

Conservative LP Setup

Single platform, moderate markup, small deposit to test the flow:

# 500 USDC on Revolut, GBP at 0.76 (slightly above market for margin)
# Min order 5 USDC, max 500 USDC, delegate bot for rate management

Multi-Platform LP

High liquidity deposit across Wise, Revolut, and Venmo for maximum fill coverage:

Dynamic Rate Adjustment

Adjust your rate based on deposit utilization. If your deposit is heavily utilized (high locked/available ratio), you can increase your rate to capture more margin:

# Check current utilization
DEPOSIT=$(cast call 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "getDeposit(uint256)((address,address,uint256,uint256,(uint256,uint256),bool,uint256,address,address,bool))" \
  $DEPOSIT_ID --rpc-url https://mainnet.base.org)

# If >80% utilized (high demand), raise rate by 1-2%
# If <20% utilized (low demand), lower rate by 1-2%
# Use setCurrencyMinRate to update
cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "setCurrencyMinRate(uint256,bytes32,bytes32,uint256)" \

Rebalancing Check

Monitor your deposit and prune expired intents to keep funds available:

# 1. Check deposit state
cast call 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "getDeposit(uint256)((address,address,uint256,uint256,(uint256,uint256),bool,uint256,address,address,bool))" \
  $DEPOSIT_ID --rpc-url https://mainnet.base.org

# 2. If lockedBalance > 0 and you suspect expired intents, prune them
cast send 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "pruneExpiredIntents(uint256)" $DEPOSIT_ID \
  --rpc-url https://mainnet.base.org --private-key $PRIVATE_KEY

# 3. Re-check -- available balance should increase after pruning
cast call 0x2f121CDDCA6d652f35e8B3E560f9760898888888 \
  "getDeposit(uint256)((address,address,uint256,uint256,(uint256,uint256),bool,uint256,address,address,bool))" \
