Channel

TIP-20 channel reserve descriptor, constants, and deterministic hashing utilities.

Channel descriptors are emitted by Channel.open and then reused to settle, top up, close, request close, withdraw, or compute the channel ID. The channel reserve precompile exposes helper methods for channel identifiers, voucher sign payloads, and its EIP-712 domain separator. These utilities compute the same values locally when the chain id and channel fields are known.

Examples

import { Channel } from 'ox/tempo'
 
const channel = Channel.from({
  expiringNonceHash: '0x0000000000000000000000000000000000000000000000000000000000000000',
  payee: '0x2222222222222222222222222222222222222222',
  payer: '0x1111111111111111111111111111111111111111',
  salt: '0x0000000000000000000000000000000000000000000000000000000000000001',
  token: 1n,
})
 
const channelId = Channel.computeId(channel, { chainId: 4217 })
