Nexus USD

Most stablecoins want to be held; Nexus USD exists mainly to move. It is the internal accounting token of Synapse, a cross-chain bridge, and every stablecoin routed between supported networks is briefly converted into nUSD before arriving on the far side. The token is fully collateralized by a pool of DAI, USDC and USDT sitting on Ethereum, and a stableswap algorithm prices it against that basket as bridging demand ebbs and flows. Because there is no company behind it, redemption is not a customer service line but a smart-contract swap: any holder can trade nUSD back into the pooled stablecoins permissionlessly, with no KYC. That makes the peg a function of pool depth rather than a bank balance, and it has generally tracked the dollar closely. It lives across a dozen chains, from Arbitrum and Optimism to Avalanche, Fantom and Aurora.
