Solana Vault Standard

GitHub: solanabr/solana-vault-standard Status: Active development — 12 variants live on devnet Maintained by: @kauenet, @thomgabriel, @vcnzo_ct and others

Overview

A standardized vault interface for Solana — the equivalent of ERC-4626 for the Solana ecosystem. Referenced in the ecosystem's sRFC 40 vault-standard discussion as an independently developed implementation.

Why It Matters

Without a standard, every DeFi protocol implements vaults differently. This makes composability painful: wallets need custom integrations for each protocol, aggregators cannot generalize across vaults, and developers reinvent the same deposit/withdraw/accounting logic repeatedly.

The Solana Vault Standard defines a common interface so that any protocol can integrate with any compliant vault — the same way ERC-4626 unified vault interactions on Ethereum.

Features

sRFC 40

SVS is referenced in the sRFC 40: Vault Standard Program discussion at solana-foundation/SRFCs as an independently developed implementation informing the emerging ecosystem vault standard (which currently prioritizes async vaults for RWA issuers).

12 Vault Variants

Reference implementations covering different DeFi use cases, all live on devnet:

• SVS-1/2 — Public vaults (live and stored balance)
• SVS-3/4 — Private vaults with Token-2022 confidential transfers
• SVS-5/6 — Streaming-yield vaults
• SVS-7 — Native SOL vault
• SVS-8 — Multi-asset basket
• SVS-9 — Allocator vault-of-vaults
• SVS-10 — Async ERC-7540-style vault
• SVS-11 — Credit-markets vault with KYC and oracle NAV
• SVS-12 — Tranched vault

Standardized Interface

A common deposit/withdraw/accounting interface adapted for Solana's account model. Handles the differences between Solana's account-based architecture and Ethereum's contract-based model.

Composability

Enables wallets, aggregators, and protocols to interact with any compliant vault through a single integration. Build once, connect to every vault.

Reference Implementations

Working Anchor programs for each vault variant. These serve as both documentation and production-ready starting points for protocol teams. The repository also ships a TypeScript SDK and a CLI.
