Spiko launched tokenized funds on Stellar in October 2025, detailing how they adapted their infrastructure to Soroban's unique constraints: TTL-based storage, sequence number limitations, and RPC data retention. They implemented channel accounts and fee bump transactions to achieve high throughput while maintaining clean authorization.
Spiko, a tokenized money market fund platform, launched on Stellar in October 2025 and documented their technical integration with Soroban smart contracts. The article covers three major challenges: implementing smart contracts in Rust with Soroban's explicit design philosophy (instance, persistent, and temporary storage types with TTLs); building a reliable indexer despite RPC limitations (7-day data retention requiring archive node fallbacks); and achieving high transaction throughput through a three-account architecture combining channel accounts for parallelism, main wallet authorization, and sponsor wallet fee management. Their solution demonstrates how multi-chain infrastructure can scale across fundamentally different blockchain models.
