MetaMask is building the single interface for all of crypto. Bitcoin is the most important chapter, and it's half-finished — users can hold BTC but can't earn on it, lend it, or use it as collateral. tBTC completes the Bitcoin story by giving MetaMask users a path from holding BTC to making it productive on-chain, extending the same DeFi access they already have for stablecoins via Aave.
Three value propositions for MetaMask:
- DeFi activation for Bitcoin — tBTC on Aave ($155M+ deposits) extends MetaMask Earn to BTC holders
- Complementary BTC bridge rail — 1:1 minting alongside ThorChain's swap model, expanding per-user fee revenue
- First BTC-to-Linea pipeline — no existing bridge provider supports BTC deposits to Linea
MetaMask: ~30M MAU, dominant EVM wallet. Native BTC support shipped Dec 2025 (hold/send/receive only — no DeFi composability). Aave stablecoin yield integration live (Jul 2025). 0.875% fee on swaps and bridges. Current BTC→EVM path: Li.Fi → ThorChain (swap-based, outputs ETH/stables).
Consensys: IPO preparation (JPMorgan, Goldman advising, 2026 target). 3 layoff rounds in 2 years. Only 3 press releases in 2025. OKX partnership as deal template (bilateral tech swap, no cash, Linea commitment appended). Lean post-layoff team prefers low-engineering-lift integrations.
Linea: zkEVM rollup. No BTC bridging solution — Wormhole doesn't support Linea, no third-party bridge handles native BTC. Minimal BTC presence on-chain. 85% of LINEA tokens allocated to ecosystem growth.
Decision-makers: Lubin (IPO narrative), IPO advisors (revenue impact), product team (bandwidth-constrained). Board sign-off likely for material partnerships.
MetaMask's multichain story needs Bitcoin to be active, not just present. tBTC as an ERC-20 makes BTC composable with everything MetaMask already offers — swaps, Aave Earn, portfolio views, the MetaMask Card ecosystem. The proposal should feel like it completes their product, not like an external integration asking for shelf space.
ThorChain serves users converting BTC into ETH/stables (one-time swap). tBTC serves users retaining Bitcoin exposure while making it productive (persistent ERC-20). Different use cases. Having both gives MetaMask the most complete Bitcoin offering in any wallet.
Fee economics: tBTC is additive. Bridge generates 0.875% MetaMask fee. Users who later swap tBTC generate additional fee events. The ERC-20 persists in the wallet ecosystem rather than passing through as a single swap.
MetaMask Earn already gives users stablecoin yield via Aave. tBTC is live on Aave with $155M+ deposits. Extending Earn to tBTC = Bitcoin holders get the same seamless yield experience. This is the most concrete, compelling pitch: "I hold BTC in MetaMask, now what?" → earn yield without leaving the wallet.
No bridge provider supports BTC deposits to Linea today. tBTC deployment requires Linea's canonical token bridge (Wormhole doesn't support Linea). This is real engineering work — frame as collaborative effort with Linea team, not a freebie. Request featured BTC asset status on Linea + Linea team co-resources the canonical bridge integration.
Technical options for Linea:
- Canonical token bridge — lock tBTC on L1, mint bridged-tBTC on Linea (~20 min L1→L2, 2-12hr L2→L1)
- Custom BridgedToken — custom tBTC contract on Linea, canonical bridge for lock/mint, Linea team coordination
- Dedicated bridge — full control, heavy engineering/audit cost
| Term | Target | Walk-Away | Notes |
|---|---|---|---|
| Phase 1: Wallet placement | 3 months featured | 2 months | Low cost, relationship builder |
| Phase 1: MM marketing | Blog + social + Snap featured | Blog mention only | Enumerate deliverables with deadlines |
| Phase 2: Integration fee | $0 | Walk if they charge | MM's stated policy: no pay-to-play |
| Phase 2: MM bridge fee | 0.875% standard | Push back if >1.0% | Let MM keep full margin — removes objection |
| Phase 2: Rev share | 5 bps above $50M cumulative | No rev share required | Signals alignment; concede to 8 bps for Linea exclusivity |
| Phase 2: Linea | 6-month featured BTC + Linea co-resources | 3 months; optional lever | Real engineering cost — ask for co-resourcing |
| Phase 1→2 pathway | Binding 60-day trigger | Written timeline, even non-binding | Key risk: Phase 1 without Phase 2 progression |
| Exclusivity | Non-exclusive | Hard walk-away | Non-negotiable |
| Removal protection | 12-month guarantee | 90-day notice minimum | Cannot be unilateral |
- Give: Generous wallet placement + tLabs leads co-marketing content → Get: Enumerated MM marketing deliverables with deadlines
- Give: tLabs does 70% of content creation → Get: Phase 2 timeline in the Phase 1 agreement
- Give: Linea deployment (real engineering) → Get: Featured BTC status on Linea + Linea team co-resources + joint announcement
- Give: 5 bps performance rev share → Get: Non-displacement guarantee (12-month minimum)
Hold firm: Non-exclusivity, no MFN, Phase 2 pathway.
| They say | Response |
|---|---|
| "We already support Bitcoin natively" | Native BTC can't access DeFi — tBTC bridges that gap. Same logic as Aave Earn for stablecoins. |
| "Just integrate through Li.Fi directly" | We can, but that forfeits co-marketing and joint narrative value for both sides. |
| "Why not WBTC or cbBTC?" | tBTC is decentralized (no single custodian), 1:1 backed with full redemption, no governance risk. Already on Aave. |
| "How does this affect our ThorChain revenue?" | Complementary, not competing. Different use cases. tBTC generates bridge fee + downstream swap fees. |
- Li.Fi conversations — begin in parallel. If tBTC routes through Li.Fi's aggregator, it appears in MM bridges without BD involvement. Best as a credible backup, not the primary path.
- Phantom/Rabby — open parallel BD conversations. Must be real. If Phantom integrates tBTC first, MM loses the narrative.
- LBTC watch — $2B TVL, 15 chains, Ledger partnership. If Lombard closes a MM deal first, tBTC's positioning narrows. Execute within 60-90 days.
Now: Deliver proposal. Begin Li.Fi and Phantom/Rabby conversations in parallel.
Weeks 1-4: Negotiate Phase 1 terms. Be generous on placement/marketing. Spend capital on Phase 2 pathway clause.
Months 2-3: Execute Phase 1 (Snap, co-marketing). Begin Phase 2 technical integration via tBTC SDK. Start Linea deployment with Linea team.
Months 3-6: Phase 2 live. Joint announcement. Collect volume data.
