Usage Example

curl -X POST "https://api.mobula.io/api/2/pm/deposit/build" \
  -H "Content-Type: application/json" \
  -d '{ "address": "0xYourWalletAddress", "amount": 100 }'

​
Integration Example

// Build deposit transaction
const res = await fetch('https://api.mobula.io/api/2/pm/deposit/build', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ address: walletAddress, amount: 100 })
});
const { data: depositTx } = await res.json();

// Send the deposit on-chain (Polygon)
await walletClient.sendTransaction({
  to: depositTx.to,
  data: depositTx.calldata,
  chain: polygon
});
This builds a simple USDC transfer() from the EOA to the Safe. The user must have sufficient USDC balance in their wallet. The Safe address is deterministically derived from the EOA address.
