Bridging

Bridging docs cover testnet bridge tooling and interoperability workflows for builders integrating Miden with external networks and intent systems.

The first guide in this section is the mock NEAR Intents 1Click-style bridge sandbox for Sepolia native ETH and public Miden testnet. Future bridge docs can be added beside it, including AggLayer bridging and Epoch bridging, without making any single guide the canonical production bridge path.

Testnet only

The current bridge sandbox is developer testing infrastructure. It is not a production bridge, not a mainnet integration path, and must not be used with mainnet funds.

Start here

Sepolia + Miden testnet

Testnet sandbox

Run the mock 1Click Bridge API locally and reproduce the Sepolia-to-Miden and Miden-to-Sepolia testing flow.

→Diagrams

Bridge flows

Understand the actors, solver role, public Miden notes, and inbound/outbound lifecycle.

→/v0

API reference

Integration shape for /v0/tokens, /v0/quote, /v0/deposit/submit, and /v0/status.

Current scope

Area	Status	Notes
Mock NEAR Intents 1Click bridge sandbox	Available	Testnet-only local service for app integration testing.
AggLayer bridging	Planned	Add as a sibling guide when the developer-facing flow is stable.
Epoch bridging	Planned	Add as a sibling guide when the developer-facing flow is stable.

When to use this section

Use these docs when you need to:

• point an app at a local mock Bridge API;
• test bridge-like quote, deposit, status, and claim flows against public testnets;
• understand how public Miden notes can represent bridge deposits or payouts;
• collect evidence with Sepolia transaction hashes and Miden transaction IDs.

For core account, note, and transaction concepts, start with the Smart Contracts section instead. For testnet RPC, explorer, faucet, and remote prover endpoints, see Network.
