Discussion

I'm a co-founder and core developer at Angle Protocol. The protocol consists of different stablecoins (EURA and USDA - USDA was newly launched in April 2024), savings solutions built on top (stEUR and stUSD) and it is governed by a token called the ANGLE token.

While we've added here the token addresses on Ethereum, these are also available on many different chains (you may find deployment addresses in Angle developers documentation). Typically USDA exists on >10 chains and it is deployed on all these chains at the same address. The same goes for stEUR and stUSD which are on different chains at the same address. EURA and ANGLE deployments across different chains come with different addresses.
