Patch Changes

viem@2.46.0

Minor Changes

• #4304 b6b50d40fb6bbadc851377b74b2dd4da584958b0 Thanks @jxom! - Breaking (viem/tempo): Renamed nonceKey: 'random' to nonceKey: 'expiring' to align with TIP-1009 terminology.

  TIP-1009 defines "expiring nonces" as time-based replay protection using validBefore timestamps. The name 'expiring' better describes the mechanism than 'random'.

  await sendTransaction(client, {
    account,
  - nonceKey: 'random',
  + nonceKey: 'expiring',
    to: '0x...',
  })
