Roadmap
The Vault is actively expanding blockchain support. This page outlines planned network additions through Q1 2027.
Roadmap timelines are estimates and subject to change. Last updated May 2026 — Solana repositioned to Q2 alongside accelerated Ed25519 delivery.
Timeline
Signing Algorithm Support
New network additions are sequenced by signing algorithm availability in The Vault’s MPC engine. The Ed25519 library has been accelerated to Q2 2026 to unblock Solana as a priority chain.
The signing scheme column below is when The Vault’s MPC library gains support for that curve — not when each chain goes live (see the timeline above for per-chain dates).
| Signing Scheme | Chains it unlocks | Curve support |
|---|---|---|
| ECDSA (secp256k1) | Ethereum, Bitcoin, TRON (live); other EVM chains, XRP, Cosmos | Now |
| Ed25519 (EdDSA) | Solana | Q2 2026 |
| Ed25519 (EdDSA) | Aptos, Sui, TON, NEAR | Q4 2026 |
| STARK curve | Starknet | Q1 2027 |
Expansion Phases
Q2 2026 — Solana + EVM Networks
Solana ships first on the new Ed25519 signing path. The remaining six EVM chains share the existing ECDSA stack and ship in parallel.
| Chain | Signing | Type |
|---|---|---|
| Solana | Ed25519 | High-throughput L1 — priority chain for institutional flows and stablecoins |
| BNB Chain | ECDSA | EVM L1 |
| Polygon PoS | ECDSA | EVM L1 |
| Arbitrum | ECDSA | EVM L2 |
| Base | ECDSA | EVM L2 |
| Optimism | ECDSA | EVM L2 |
| Avalanche | ECDSA | EVM (C-Chain) |
Q3 2026 — Enterprise & Regional Networks
Strategic networks targeting institutional finance and regulated markets. Both use ECDSA.
| Chain | Type | Ecosystem |
|---|---|---|
| Canton Network | Permissioned enterprise chain | DTCC, BNY Mellon, Goldman Sachs |
| ADI Chain | Institutional L2 (zkSync-based) | UAE Central Bank licensed |
Q4 2026 — Remaining Ed25519 Networks
The EdDSA library lands in Q2 with Solana; the remaining Ed25519 chains ship as a coordinated batch in Q4 once the signing library is fully hardened across additional VM targets.
| Chain | Signing | Notes |
|---|---|---|
| Aptos | Ed25519 | Move VM |
| Sui | Ed25519 | Move VM — shared Aptos infrastructure |
| TON | Ed25519 | Custom TL-B serialization |
| NEAR Protocol | Ed25519 | Aurora EVM L2 compatibility |
Q1 2027 — Ecosystem & ZK Networks
| Chain | Signing | Notes |
|---|---|---|
| Cosmos / IBC | ECDSA (secp256k1) | Unlocks the full IBC ecosystem (ATOM, INJ, OSMO, dYdX, Celestia) |
| Starknet | STARK curve | ZK-native, separate signing implementation |
