最新报道:According to Bijie.com, Solana Improvement Proposal SIMD-0268 has been accepted (the next step is a community vote on whether to activate it), raising the cross-program invocation (CPI) nesting limit from 4 to 8. This proposal aims to increase the complexity of dApp interoperability, allowing more inter-program calls within a single transaction, thereby improving the overall composability of the network. Cross-program invocation (CPI) is a method for programs to call each other. Perpetual swaps (Perps) often require multiple program calls for position management, liquidation, and cross-margin operations. The previous 4-level nesting limit restricted these interactions; increasing it to 8 levels will enable deeper single-transaction interactions and clearer composability.
