feat: v1

[jxom]

Breaking changes

• Hex-encoded crypto coordinates. Migrated Signature, PublicKey, BlsPoint, and all envelope types (Transaction, Authorization, ERC envelopes, Tempo) from bigint r/s/x/y/Fp/Fp2 to padded Hex.Hex (32-byte for secp256k1/P256/WebAuthnP256, 48-byte for BLS12-381). The bigintType generic is removed.

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

• @noble/* v2. Upgraded @noble/ciphers, @noble/curves, @noble/hashes, @scure/bip32, @scure/bip39. ECDSA signatures (Secp256k1, P256) now default to lowS: true. Module .noble re-exports follow v2 (randomSecretKey, Point, bls.longSignatures.*, etc.).

• PeerDAS (EIP-7594) blob model. Removed the EIP-4844 blob-sidecar surface (Blobs.toSidecars, Blobs.BlobSidecar(s), TxEnvelopeEip4844.sidecars, Kzg.Kzg.computeBlobKzgProof). Added the BlobCells module for cell/column propagation. KZG backends must implement computeCells, computeCellsAndKzgProofs, recoverCellsAndKzgProofs, verifyCellKzgProofBatch.

  - sidecars: { blobs, commitments, proofs }
  + sidecars: { blobs, commitments, cellProofs }

• ABI decode checksums by default. AbiParameters.decode (and downstream AbiFunction/AbiEvent/AbiError decoders) checksum decoded address outputs. Opt out with checksumAddress: false.

Notable additions

• Crypto serialized inputs and as option. Secp256k1, P256, WebCryptoP256, and Bls now accept Hex.Hex | Bytes.Bytes | Signature.Signature | PublicKey.PublicKey for signature/publicKey params, and expose as: 'Hex' | 'Bytes' | 'Object' on sign / getPublicKey / recoverPublicKey.

  - const signature = Secp256k1.sign({ payload, privateKey })
  + const signature = Secp256k1.sign({ payload, privateKey, as: 'Hex' })

• AbiEvent.decodeLog. Extract and decode an event log directly from an ABI.

  const abi = Abi.from([
    'event Transfer(address indexed from, address indexed to, uint256 value)',
  ])
  
  const { event, args } = AbiEvent.decodeLog(abi, {
    data: '0x0000000000000000000000000000000000000000000000000000000000000001',
    topics: [
      '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef',
      '0x000000000000000000000000a5cc3c03994db5b0d9a5eedd10cabab0813678ac',
      '0x000000000000000000000000a5cc3c03994db5b0d9a5eedd10cabab0813678ac',
    ],
  })
  // event: { name: 'Transfer', type: 'event', ... }
  // args:  { from: '0xa5cc...', to: '0xa5cc...', value: 1n }

• AbiEvent.extractLogs. Filter and decode logs from a batch against an ABI.

  const logs = AbiEvent.extractLogs(abi, logs, { eventName: 'Transfer' })
  // [{ eventName: 'Transfer', args: { from, to, value }, topics, data }, ...]

• AbiError.extract. Select the matching ABI error from revert data and decode its arguments.

  const abi = Abi.from([
    'error InvalidSignature(uint r, uint s, uint8 yParity)',
  ])
  
  const { error, args } = AbiError.extract(
    abi,
    '0xecde6349...0001a4...0045...0001',
  )
  // error: { name: 'InvalidSignature', type: 'error', ... }
  // args:  [420n, 69n, 1]

• AbiFunction.decodeData selector inference. Pass an ABI plus calldata and the function is resolved from the 4-byte selector. Decoding selector-only calldata for a function with inputs now throws AbiParameters.DataSizeTooSmallError instead of silently returning undefined, and constructorless AbiConstructor deploy data is now allowed when there are no arguments.

  const abi = Abi.from(['function approve(address, uint256)', /* ... */])
  
  const input = AbiFunction.decodeData(
    abi,
    '0x095ea7b3000000000000000000000000d8da6bf26964af9d7eed9e03e53415d37aa960450000000000000000000000000000000000000000000000000000000000010f2c',
  )
  // ['0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045', 69420n]

• Transaction envelope router. TxEnvelope.from / serialize / deserialize / hash / getSignPayload / toRpc infer the envelope type from input properties and route to the matching TxEnvelopeLegacy / TxEnvelopeEip2930 / TxEnvelopeEip1559 / TxEnvelopeEip4844 / TxEnvelopeEip7702 module.

  const envelope = TxEnvelope.from({
    chainId: 1,
    maxFeePerGas: 1n,
  })
  
  const serialized = TxEnvelope.serialize(envelope, { signature })
  const hash = TxEnvelope.hash(envelope)
