PROTOCOL

ECDSA signatures, verifiable online

Every request signed with secp256k1 private key, hashed with Keccak-256, with public key and timestamp in headers.

01
Build payload
body + 8-byte little-endian Unix timestamp
02
Hash
Keccak-256(payload) → 32 bytes
03
Sign
secp256k1 private key → 65 bytes (v + r + s)
04
Send
X-Signature / X-Public-Key / X-Signature-Timestamp headers
Try in API Tester
sign-request.ts
// 1. build payload
const payload = body + timestamp

// 2. keccak-256 hash
const hash = keccak256(payload)

// 3. secp256k1 sign
const sig = sign(hash, privateKey)

// 4. headers
X-Signature: 0x{65 bytes hex}
