From 1493f4941691c36f85a4fbf631a09c0da26de2c3 Mon Sep 17 00:00:00 2001 From: akildemir <34187742+akildemir@users.noreply.github.com> Date: Fri, 19 Jul 2024 02:30:19 +0300 Subject: [PATCH] Implement genesis liquidity protocol (#545) * add genesis liquidity implementation * add missing deposit event * fix CI issues * minor fixes * make math safer * fix fmt * make remove liquidity an authorized call * implement setting initial values for coins * add genesis liquidity test & misc fixes * updato develop latest * fix rotation test * Finish merging develop * Remove accidentally committed ETH files * fix pr comments * further bug fixes * fix last pr comments * tidy up * Misc --------- Co-authored-by: Luke Parker --- Cargo.lock | 37 ++ deny.toml | 2 + substrate/abi/Cargo.toml | 4 +
