LINK on Ethereum

The details.

NetworkEthereum · ERC-20 token
Contract0x514910771AF9Ca656af840dff83E8264EcF986CA View on explorer
Only this contract is accepted as LINK on Ethereum: look-alike tokens sent to your customers' addresses are ignored.
Decimals18 (amounts in the API are whole numbers of the smallest unit)
DepositsA deposit counts once it is 12 blocks deep and its block is still part of the chain. If a reorganization removes it, it's never credited.
Minimum withdrawal1 LINK
Network feesNetwork fees are paid in ETH. Your gas wallet can top up the ETH that token payouts and sweeps need, within a daily cap you set.
AddressesEvery wallet has one EVM address (0x…), the same on Ethereum, BNB Chain, Base, Polygon and Lisk. A customer can send any supported coin on any of those networks to it.

For developers

Deposit addresses and payouts in a few lines.

import { Valtu, depositAddress } from "@valtu/wallet-kit";
const valtu = Valtu.fromEnv();

// A deposit address for one of your customers (idempotent).
const wallet = await valtu.wallets.forCustomer("cus_42");
const address = depositAddress(wallet, "ethereum");

// A payout of 1.5 LINK: retries never send twice.
const amount = await valtu.assets.toBaseUnits("LINK-ERC20", "1.5");
await valtu.transfers.create({ walletId: payoutWalletId, asset: "LINK-ERC20", amount, to, externalId: "payout_981" });

Python: pip install valtu, same calls (valtu.wallets.for_customer, valtu.transfers.create). Full guide: integration.
