Function createERCDepositData

Constructs the deposit data for an EVM-Substrate bridge transaction.

Example

// Amount of tokens:
const amount = '1';
// EVM address
const evmAddress = '0x1234567890123456789012345678901234567890';
// Decimals of the token
const decimals = 18;
createERCDepositData(amount, evmAddress, decimals);

Example

import { decodeAddress } from '@polkadot/util-crypto';
// Substrate MultiLocation
// Decode address to bytes of public key
const addressPublicKeyInBytes = decodeAddress(
  '5CDQJk6kxvBcjauhrogUc9B8vhbdXhRscp1tGEUmniryF1Vt',
);
// Convert bytes of public key to hex string
const addressPublicKeyHexString = ethers.utils.hexlify(addressPublicKeyInBytes);
// console.log(addressPublicKeyHexString) => "0x06a220edf5f82b84fc5f9270f8a30a17636bf29c05a5c16279405ca20918aa39"
const multiLocation = JSON.stringify({
  parents: 0,
    interior: {
      X1: {
        AccountId32: {
          network: { any: null },
          id: addressPublicKeyHexString,
        },
      },
    },
  })
// Amount of tokens:
const amount = '2';
createERCDepositData(amount, multiLocation);

Returns

The deposit data as hex string
