@meow tapped Seismic to power its stablecoin accounts and stablecoin payments.
A business banking platform chose to build core financial infrastructure on a privacy-first L1. Here's what that actually means
🧵
Meow is a business banking platform, checking, corporate cards, global payments, treasury, and invoicing all in one dashboard.
The whole thing is built around keeping costs low and passing savings back to businesses. Simple, no-frills infrastructure for companies that just need it to work.
---
Adding stablecoin accounts and payments to that stack means transaction data lives on-chain.
For a business banking platform, that's a real problem. Payroll, vendor payments, treasury balances, account activity,that's sensitive financial data sitting on a public ledger anyone can read.
---
@SeismicSys handles this at the protocol level.
Calldata is encrypted before it leaves the user's machine. The encryption uses ECDH key agreement between the user's private key and the network's TEE public key,the plaintext never touches the mempool.
---
On-chain storage is shielded at the opcode level.
Private variables write via CSTORE and read via CLOAD. Query a shielded slot through standard RPC and you get zero back, it looks like uninitialized storage to anyone watching.
---
The nodes run inside Intel TDX Trusted Execution Environments.
The host OS, the hypervisor, the node operator, none of them can read what's being processed. Encryption keys are generated inside the TEE at genesis and never leave it.
---
Meow needed stablecoin infrastructure that could handle real business financial data with real privacy requirements.
Building on Seismic means account balances and payment flows are private by default, enforced at the protocol level, not patched on top.
---
Seismic is backed by a16z with $17M raised, and fintech companies are already building core products on it.
The privacy layer for onchain finance is taking shape.
