Verify Ethereum & ERC20 Payments via API — Real-Time, Non-Custodial

Quick Answer: ShegerPay verifies Ethereum (ETH) and ERC20 token payments through native on-chain verification via one REST API call. The customer sends ETH or any ERC20 to the merchant's Ethereum address, the chain confirms, and ShegerPay's webhook fires with payment.verified. Default confirmation count is 12. ShegerPay never holds the funds — no merchant license required.

What is Ethereum?

Ethereum is the second-largest cryptocurrency by market cap and the largest smart-contract platform. Its native asset is ETH, but the network also hosts thousands of ERC20 tokens including USDT, USDC, DAI, and most major stablecoins. Ethereum is widely used by Ethiopian crypto users and merchants for stablecoin payments and DeFi interactions.

How Ethereum verification works with ShegerPay

1. Customer sends ETH or an ERC20 token from their wallet/exchange to the merchant's Ethereum address
2. Ethereum broadcasts and confirms the transfer (~12s/block)
3. Merchant backend POSTs to /api/v1/verify with provider=ethereum, tx hash, and optional token (for ERC20)
4. ShegerPay reads the chain via its full-node infrastructure, returns verified=true once confirmations are met, then fires the webhook

Code example

curl -X POST https://api.shegerpay.com/api/v1/verify \
  -H "X-API-Key: sk_test_demo" \
  -H "Content-Type: application/json" \
  -d '{"provider":"ethereum","transaction_id":"0xabc123...","amount":0.1,"token":"ETH"}'

import ShegerPay from '@shegerpay/sdk';
const sp = new ShegerPay('sk_test_demo');
const result = await sp.verify({
  provider: 'ethereum',
  transactionId: '0xabc123...',
  amount: 100,
  token: 'USDC' // ERC20 token symbol or contract address
});

from shegerpay import ShegerPay
sp = ShegerPay('sk_test_demo')
result = sp.verify(provider='ethereum', transaction_id='0xabc123...', amount=100, token='USDC')

$sp = new ShegerPay\Client('sk_test_demo');
$result = $sp->verify([
  'provider' => 'ethereum',
  'transaction_id' => '0xabc123...',
  'amount' => 100,
  'token' => 'USDC'
]);
