Unified addresses
How 2D treats Ethereum (0x…) and Tron (T…) addresses as the exact same account, with both encodings kept in sync on the wire.
2D
A Layer-1 network built for stablecoin payments, uniting Ethereum and Tron under one account state with zero gas fees and instant finality.
Why build on 2D?
Section titled “Why build on 2D?”2D is a Layer-1 blockchain built for fast, free stablecoin payments. It unifies the Ethereum and Tron ecosystems under a single account state, which removes friction for both users and developers.
- One account, two ecosystems. The same account state works with both Ethereum JSON-RPC (MetaMask, viem) and the Tron HTTP API (TronLink). A transfer sent from TronLink shows up in MetaMask right away.
- EVM-compatible API, no EVM. Standard Ethereum tools work out of the box. Instead of a bytecode interpreter, every piece of on-chain logic is a small, auditable native module (a precompile).
- Zero gas fees. Every transaction is free. A sliding-window throttle slows spam down instead of charging gas, so legitimate senders get delayed rather than priced out.
- Instant finality. A block is final the moment it is produced. No confirmations to wait for and no mempool to manage, which suits point-of-sale payments.
- Verifiable security. Independent read-only verifiers replay and validate every block before serving state to wallets, and reject anything that fails the check.
Explore the architecture
Section titled “Explore the architecture”Precompiles, no EVM
On-chain logic as Elixir modules at fixed addresses, without the overhead and attack surface of a bytecode interpreter.
Bridge (HTLC)
How 2D moves USD-stable across chains with no wrapped-bridge custody pool and no unlock authority: preimage-locked HTLC settlement, re-checked against finalized Ethereum state by every verifier.
State roots
The cryptography behind the chain. Each block carries a fingerprint of mutable state, so clients can verify network integrity on their own.
Gasless transactions
The mechanics of a free network: how the sliding-window throttle stops spam while keeping user transactions cost-free.
Security model
The trust boundaries between users, block producers, and verifiers. How 2D validates input and prevents replay attacks.
Agent Gateway
Authenticated, rate-limited read access for autonomous agents, with no signing key handed to the agent. Per-agent wallets are bound to keys held inside a TEE signer; write endpoints arrive later.
Run a verifier
Step-by-step setup of a read-only node that validates every block and serves verified state to the world.
