Research and Development Into Pegged Cryptocurrency Assets

57 repositories collecting every major stablecoin contract, wrapped asset, gold-pegged token, and algorithmic peg mechanism deployed on-chain.


What This Is

tethercoin is the definitive stablecoin source code library — a focused collection of every major pegged asset smart contract across fiat-backed (USDT, USDC, BUSD, USDP), crypto-backed (DAI, USDA, USM), gold-backed (PAXG, CACHE, Digix), wrapped (WETH, wBTC), and algorithmic (Curve, Ampleforth) stablecoins.

The logic: if a token is pegged to a real-world value, its source code belongs here.
