Major Changes

• #231 40d9408 Thanks @jxom! - Breaking: Changed ABI decode helpers to checksum decoded addresses by default.

  - AbiParameters.decode(parameters, data)
  + AbiParameters.decode(parameters, data, { checksumAddress: false })

• #231 40d9408 Thanks @jxom! - Removed the Tempo TokenId module and narrowed Tempo token inputs (feeToken, Channel.token, PoolId.from tokens) to Address.Address; also removed the now-redundant Channel.Resolved type.

    TxEnvelopeTempo.from({
      // ...
  -   feeToken: 1n,
  +   feeToken: '0x20c0000000000000000000000000000000000001',
    })

• #231 40d9408 Thanks @jxom! - Upgraded @noble/ciphers, @noble/curves, @noble/hashes, @scure/bip32, and @scure/bip39 to v2.

  Notable behavioral changes inherited from noble v2:

  • ECDSA signatures now default to lowS: true for both Secp256k1 and P256. Previously P256 signatures could have high-S values.
  • The noble re-exports on Secp256k1, P256, Ed25519, X25519, and Bls now reference the v2 APIs (e.g. randomSecretKey() instead of randomPrivateKey(), Point instead of ProjectivePoint/ExtendedPoint, bls.longSignatures.* instead of top-level bls.sign/verify). If you depended on the v1 shape via Module.noble, refer to the noble v2 changelog.

• #231 40d9408 Thanks @jxom! - Breaking: Removed the 4844-only blob-sidecar surface in favor of PeerDAS
  (EIP-7594).

  • Kzg.Kzg no longer includes computeBlobKzgProof. Bring a PeerDAS-capable
    backend (e.g. c-kzg ≥ v1.5, micro-eth-signer/advanced/kzg.js ≥ v0.18, or
    equivalent). The backend must implement computeCells,
    computeCellsAndKzgProofs, recoverCellsAndKzgProofs, and
    verifyCellKzgProofBatch in addition to blobToKzgCommitment.
  • Removed Blobs.toSidecars, Blobs.toProofs,
    Blobs.sidecarsToVersionedHashes, Blobs.BlobSidecar, and
    Blobs.BlobSidecars. Use the upcoming BlobCells module (next phase) for
    PeerDAS data-column construction. Kzg.Kzg.blobToKzgCommitment and
    Blobs.toVersionedHashes remain for transaction versioned-hash derivation.
  • Removed TxEnvelopeEip4844.sidecars (the legacy "network wrapper" RLP form
    for eth_sendRawTransaction). PeerDAS replaces the network wrapper with
    cell/column propagation; the on-chain envelope is unchanged.

• #231 40d9408 Thanks @jxom! - Migrated ECDSA and BLS coordinate fields (r, s, x, y, BLS Fp/Fp2) from bigint to padded Hex.Hex strings (32-byte for secp256k1/P256/WebAuthnP256, 48-byte for BLS12-381) on Signature, PublicKey, BlsPoint, Transaction, Authorization, TxEnvelope, and related Tempo and ERC envelopes, dropping the bigintType generic.

  - Signature.from({ r: 0x6e10...n, s: 0x4a90...n, yParity: 1 })
  + Signature.from({
  +   r: '0x6e100a352ec6ad1b70802290e18aeed190704973570f3b8ed42cb9808e2ea6bf',
  +   s: '0x4a90a229a244495b41890987806fcbd2d5d23fc0dbe5f5256c2613c039d76db8',
  +   yParity: 1,
  + })

• #231 40d9408 Thanks @jxom! - Removed the TempoAddress module and its tempox-prefixed address format. All Tempo modules now accept plain hex Address.Address values; remove any TempoAddress.format / TempoAddress.parse / TempoAddress.resolve calls at the boundary. The addressType type parameter has also been dropped from Call, TxEnvelopeTempo, KeyAuthorization, AuthorizationTempo, TransactionRequest, and TokenId.TokenIdOrAddress.

  - import { TempoAddress } from 'ox/tempo'
  - const formatted = TempoAddress.format('0x742d35Cc6634C0532925a3b844Bc9e7595f2bD28')
  - const { address } = TempoAddress.parse(formatted)
  + const address = '0x742d35Cc6634C0532925a3b844Bc9e7595f2bD28'

Minor Changes

• #231 40d9408 Thanks @jxom! - Added an AbiFunction.decodeData(abi, data) overload that extracts the ABI function from the calldata selector.

• #231 40d9408 Thanks @jxom! - Added human-readable ABI parsing and formatting utilities from abitype to ox, including runtime validation and type-level safety for Abi, AbiItem, AbiParameters, and the new AbiParameter module.

• #231 40d9408 Thanks @jxom! - Added AccountProof.fromRpc and AccountProof.toRpc for converting between RPC and instantiated AccountProof shapes returned by eth_getProof.

• #231 40d9408 Thanks @jxom! - Added Bloom.prepare, Bloom.containsPrepared, and Bloom.containsHash for membership checks against a precomputed bloom filter. Use Bloom.prepare(bloom) once and Bloom.containsPrepared(prepared, input) (or Bloom.containsHash(prepared, hash) when the caller already has the keccak hash) inside hot loops to avoid the per-call Bytes.fromHex allocation that Bloom.contains pays.

• #231 40d9408 Thanks @jxom! - Added returnByteLength and returnDecoded options to CoseKey.toPublicKey and accepted Uint8Array input in addition to Hex.

• #231 40d9408 Thanks @jxom! - Added as: 'Hex' | 'Bytes' | 'Object' option to Secp256k1.sign / getPublicKey / recoverPublicKey, P256.sign / getPublicKey / recoverPublicKey, WebCryptoP256.sign, and Bls.sign / getPublicKey (default 'Object' keeps existing behavior); plus accept Hex.Hex | Bytes.Bytes | Signature.Signature for signature params and Hex.Hex | Bytes.Bytes | PublicKey.PublicKey for publicKey params on verify, recoverAddress, recoverPublicKey, getSharedSecret across the same modules.

• #231 40d9408 Thanks @jxom! - Added EntryPoint 0.9 ABI, address, UserOperation types, paymasterSignature packing, hashing, and RPC support.

• #231 40d9408 Thanks @jxom! - Added Fee.fromHistoryRpc, Fee.toHistoryRpc, Fee.estimateMaxFeePerGas, and Fee.effectiveGasPrice for converting between RPC/instantiated FeeHistory shapes and computing common EIP-1559 fee values.

• #231 40d9408 Thanks @jxom! - Added the EIP-234 blockHash branch to Filter.Filter (and Filter.Rpc) so log filters can be discriminated against fromBlock/toBlock and blockHash, matching the execution-apis filter.yaml oneOf schema. Filter.toRpc now forwards blockHash when present.

• #231 40d9408 Thanks @jxom! - Added directional codec helpers to the ox/zod RpcSchema namespace: decodeParams/encodeParams, decodeReturns/encodeReturns, and decodeRequest/encodeRequest (decode maps wire → native, encode maps native → wire), alongside parseItem for method lookup and parse as an alias of decodeRequest. Scalar quantity returns in z.RpcSchema.Eth now decode to their native representation (eth_blockNumber, eth_gasPrice, eth_blobBaseFee, eth_estimateGas, eth_getBalance, eth_maxPriorityFeePerGas → bigint; eth_chainId, eth_getTransactionCount, eth_getBlockTransactionCountBy*, eth_getUncleCountByBlock* → number), while raw transport typing (RpcSchema.FromZod) continues to use wire types.

• #231 40d9408 Thanks @jxom! - Added Zod-backed RPC schema support: z.RpcSchema.from (in ox/zod) now accepts a record of { params, returns } Zod schemas keyed by method name and returns a parseable RpcSchema.Namespace; RpcSchema.Schema/RpcSchema.ToGeneric/RpcSchema.FromZod were added; and Provider.from / RpcTransport.fromHttp accept a Zod namespace as their schema option, deriving request/return types from it.

Patch Changes

• #281 da3309e Thanks @jxom! - Breaking (ox/tempo): Removed the TIP-1061 multisig config_id concept to match the updated Tempo reference implementation: multisig account addresses now derive directly from the initial config, owner approval digests bind only account, the signature wire format is 0x05 || rlp([account, signatures, init?]), MultisigConfig.maxOwners is now 255 with u8 weights, and owner approvals may be nested multisig signatures.

  - const id = MultisigConfig.toId(genesisConfig)
  - const account = MultisigConfig.getAddress({ genesisConfigId: id })
  + const account = MultisigConfig.getAddress(genesisConfig)
  
  - MultisigConfig.getSignPayload({ payload, account, genesisConfigId })
  + MultisigConfig.getSignPayload({ payload, account })
  
  - SignatureEnvelope.from({ account, genesisConfigId, signatures })
  + SignatureEnvelope.from({ account, signatures })
