Supported Currency Pairs¶

Sera supports stablecoin trading across many fiat currencies. Each currency is represented by one or more stablecoins on Ethereum.

Available Currencies¶

The table below reflects the Ethereum mainnet token registry. Other deployments (Sepolia testnet, etc.) carry a different subset — query GET /tokens for the live list, which is the authoritative source.

Trading Pairs¶

Trading pairs on Sera are identified on-chain by the base and quote token contract addresses. For display, each pair is rendered as BASE_SYMBOL/QUOTE_SYMBOL using the ERC-20 tokens' display tickers — so a Euro-vs-Dollar market between EURC and USDC shows as EURC/USDC, not EUR/USD. Pair orientation is canonicalised server-side (smaller lowercased address becomes base), and the display string reflects that canonical orientation.

You can trade any combination of supported stablecoins. Common pairs include:

• EURC/USDC — Euro stablecoin vs US Dollar stablecoin
• TGBP/USDC — British Pound stablecoin vs US Dollar stablecoin
• XSGD/USDC — Singapore Dollar stablecoin vs US Dollar stablecoin
• JPYC/USDC — Japanese Yen stablecoin vs US Dollar stablecoin

Exact pair strings depend on which specific stablecoins are registered — a deployment that lists EURT instead of EURC will render the Euro pair as EURT/USDC. Query GET /api/v1/markets for the live list.

Querying Available Tokens¶

Use the API to get the current list of supported tokens:

curl https://api.sera.cx/api/v1/tokens

const response = await fetch('https://api.sera.cx/api/v1/tokens');
const { tokens } = await response.json();
console.log(tokens);

import requests

response = requests.get('https://api.sera.cx/api/v1/tokens')
tokens = response.json()['tokens']
print(tokens)
