SDF protocol developers debate CAP-84, which proposes adding MUXing support to contract accounts. Discussion covers use cases for exchanges and custodial platforms, with consideration of protocol-level support vs. Soroban-based implementations.
Stellar Developers Meeting explores CAP-84 and CAP-86. The primary discussion focuses on MUXing support for contract accounts (C accounts), a feature that currently exists for regular G accounts. Jake Urban presents the use case: exchanges and custodial platforms need to support deposits to omnibus accounts with per-transaction identifiers, which today requires protocol-level MUXing or memo fields that contracts cannot access. George raises an architectural consideration: whether Soroban's programmability could replicate the feature without protocol changes. The consensus leans toward protocol support for consistency and developer experience, avoiding fragmented implementations across the ecosystem.
