# SwapEazi
> Cross-chain stablecoin routing infrastructure. One API routes stablecoin swaps
> across seven networks — Ethereum, Base, Solana, Polygon, Arbitrum, Optimism,
> BNB Chain — plus Tron / USDT-TRC20 corridors that generic aggregators won't
> serve (Jumper Exchange returns "No routes available" on USDT-TRC20 ↔ USDC-Base).
> Wallet compliance screening on every swap, batch disbursement, and a
> 0.5% all-in flat fee (gas + bridge + DEX + slippage inclusive). Non-custodial,
> no sign-up. Used by remittance operators, payroll platforms, DeFi agents,
> merchants, and individuals — with structural focus on the SADC corridor and
> EU diaspora flows post-MiCA.

## Who we are
SwapEazi is stablecoin routing infrastructure for the global on-chain economy.
Remittance companies, payroll platforms, wallets, and AI agents integrate
SwapEazi as their routing layer. End users can also swap directly at
https://swapeazi.io/app.

## What makes us different
- **Tron / USDT-TRC20 corridor coverage.** Jumper, Li.Fi consumer, and most
  generic aggregators deprioritise non-EVM Tron — yet USDT on Tron is the
  dominant stablecoin by tx volume in SSA/SADC. SwapEazi routes
  USDT (Tron) ↔ USDC (Base/Polygon) and USDT (Tron) ↔ EURC (Base) — the
  pairs structurally created by MiCA pushing EU diaspora to USDC/EURC
  while SADC recipients hold USDT-TRC20.
- Infrastructure, not a widget: modular compliance (GoPlus live;
  Chainalysis and TRM Labs drop in via env flag), multi-factor route
  scoring, and a proprietary route-intelligence data layer that improves
  with every execution.
- One flat 0.5% fee — gas, bridge, DEX and slippage included; no hidden
  spread, no positive-slippage capture. The quote you see is the number
  the recipient receives. Benchmarked against the World Bank-audited
  6.34% SADC corridor average.
- Global corridors: USD, EUR, GBP stablecoins plus emerging-market pegs
  (KES, NGN, ZAR, GHS and more) across 7 chains plus Tron.
- Non-custodial: we never hold user funds.

## Public API surface (key-authenticated)
- GET  /api/v1/chains     — supported networks, tokens, and corridors
- GET  /api/v1/corridors  — available trading pairs with liquidity metadata
- POST /api/v1/quote      — ranked routes with fee, timing, slippage
- POST /api/v1/swap       — execute and settle (single)
- POST /api/v1/swap/batch — batch disbursement, up to 50 recipients per call
- POST /api/v1/screen     — standalone wallet compliance screening

Every request passes wallet + path compliance screening before routing.
High-risk and sanctioned wallets are blocked automatically.

## Pricing
0.5% flat per swap, all-in (gas + bridge + DEX + slippage inclusive).

## Agent Payments — x402 (Coinbase / agentic.market)
Agents can call the swap endpoint with no API key by paying $0.02 USDC
on Base per call using the x402 payment protocol.

- GET  /.well-known/x402.json  — machine-readable capability manifest
- POST /api/x402/quote         — free quote (no payment)
- POST /api/x402/swap          — paid swap ($0.02 USDC on Base via x402)

The endpoint returns HTTP 402 with payment requirements on the first call.
Submit payment via X-PAYMENT header; on success the swap transaction is
returned with an X-PAYMENT-RESPONSE receipt header.

## Agent Payments — MPP / Tempo
