MAKING SOLANA COMPOSABLE

Summary from the TLDR Crypto newsletter

Solana's 1,232-byte transaction limit and accounts model make complex multi-hop swaps impossible compared to Ethereum, where 50-hop swaps across 37 tokens work trivially, with Account Lookup Tables providing cumbersome workarounds requiring V0 transactions and prior construction. There are three solutions: validator-side account lookups allowing automatic derivation instead of payload inclusion, top-level return value passing eliminating scratch accounts for instruction composition, and native bundling with instruction-level signatures removing round-trip bottlenecks between parties. Widespread bundling adoption, massive instructions, and core infrastructure's ALT reliance signal the network wants composability as markets mature toward more expressive applications. Proposed changes enable high-frequency off-chain apps using Solana for atomic settlement.
