THORChain Weekly Dev Update for Week 93, 15–23 May; MCCN V0.52.0, MCCN V0.53.1, BitcoinCash Bug, Midgard Continuous Aggregation, THORWallet, Community Updates

Summary

RAISETHECAPS

The caps were raised to 1.5m RUNE in order to increase load on the network. A lot of issues out of this event were subsequently fixed.

Multichain — Some Edge Cases

MCCN hit a snag with BitcoinCash address changes. XChainJS was amended upstream to revert back to legacy addresses (due to UX problems), but it was not known to anyone at the time that BitcoinCash underhandedly converts legacy addresses to new “cash” addresses. This means THORChain sent a swap to a legacy address, which was converted on-chain to a different address, and could not identify it. It then assumed it wasn’t done and kept scheduling the swap. The member received their BCH swap 18 times before a emergency release was sent out to stop it.

THORChain is censorship-resistant, which means swaps are retried until done correctly.

Luckily the member reached out and returned 90% of the funds (keeping a 10% bounty). 💚

Additionally an update was released to make the Router compatible with wrapping smart contracts.
