Most @base bugs trace to one mistake: reading "latest" where the code needed "safe".
5 confirmation tiers you should know:
β Flashblock: 200ms, sequencer preconf
β latest: 2s, reversible
β safe: 5β10 min, batch on Ethereum
β finalized: 15β20 min, validators signed off
β withdrawal: 7 days
Crediting a deposit on "latest" is how you lose money.

Next up in our $49/mo global RPC showdown is #Arbitrum One mainnet with @DwellirOfficial vs. @ChainstackHQ for JSON-RPC and WebSocket from 31 locations.
Based on 30 runs over the course of 5 consecutive days, it appears to us that Chainstack achieves a perfect win with 45 to 0 possible major performance metrics for HTTPS and WSS;
Both Dwellir and Chainstack had perfect 100% blockNumber consistency and 0 fails across 15 JSON-RPC runs; block availability dipped under 100% for both but only due to βemptyβ blocks;
During the runs with WebSocket, we observed 1 timeout for Dwellir from SΓ£o Paulo during warmup; while Chainstack had a total of 6 broken / premature connections out of the 465 (31 locations * 15 rounds).
Btw, results for Base mainnet are in x.com/CompareNodes/status/20β¦
