Overview

remit.md Ruby SDK - universal payment protocol for AI agents.

Examples:

Direct payment

wallet = Remitmd::RemitWallet.new(private_key: ENV["REMITMD_PRIVATE_KEY"])
tx = wallet.pay("0xRecipient0000000000000000000000000000001", 1.50)
puts tx.tx_hash

Using MockRemit in tests

mock   = Remitmd::MockRemit.new
wallet = mock.wallet
wallet.pay("0x0000000000000000000000000000000000000001", 1.00)
mock.was_paid?("0x0000000000000000000000000000000000000001", 1.00) # => true

VERSION =

CHAIN_CONFIG = Chain configuration: maps chain names to (api_url, chain_id) pairs. Canonical keys use hyphens; underscored variants are accepted as aliases.

SECP256K1_P = secp256k1 field prime p (constant - never changes)

OpenSSL::BN.new(
  "FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F", 16
).freeze

SECP256K1_SQRT_EXP = Precomputed (p + 1) / 4 - the modular square root exponent for p ≡ 3 (mod 4). Avoids BN division at runtime (which returns Integer on some OpenSSL versions).

CONTRACT_TO_FLOW = Contract name -> flow name for /permits/prepare.
