Bitcoin Signet Faucet

About Bitcoin Signet & This Faucet

This page provides access to a Bitcoin Signet Faucet. Signet is a specialized Bitcoin test network where developers can mint, send, and receive test assets without real-world costs. Whether you are building a Bitcoin wallet, testing Lightning Network integrations, or experimenting with advanced scripting features, Signet provides a stable and reliable environment for your work.

What is Bitcoin Signet?

Bitcoin Signet is a test network introduced in BIP-325 that solves many of the problems developers faced with the older Testnet. Unlike Testnet, where anyone can mine blocks and the network can be unstable, Signet requires blocks to be signed by a trusted authority — making it predictable and reliable for development.

• Test Network: Signet allows developers to safely test Bitcoin features in a controlled environment, avoiding costs and risks associated with mainnet BTC.
• Customizable and Permissioned: Unlike Testnet, Signet prevents spam by requiring block signatures for block production. This makes it ideal for focused experimentation and testing.
• Consistent Block Times: Signet produces blocks at regular ~10 minute intervals, closely mimicking mainnet behavior — unlike Testnet which can have erratic block times.
• Developer-Friendly OP_CODES: Signet is being actively used to test several proposed OP_CODES and advanced features that could enable new Bitcoin use cases:
  • OP_CTV (CheckTemplateVerify): Enables transaction "covenants," where spending outputs must follow specific predefined templates. This allows for trustless vaults, batching and congestion control, and advanced payment channels for layer-2 scaling solutions.
  • OP_CAT (Concatenate): Originally removed from Bitcoin, OP_CAT is being explored to allow concatenation of data in scripts, enabling more dynamic and programmable Bitcoin transactions.
  • OP_APO (AnyPrevOut): Allows BIP-118 "SIGHASH_ANYPREVOUT," enabling transactions that do not commit to a specific input — useful for Eltoo payment channels and improved fee management.

Why Use a Faucet?

Since Signet BTC has no monetary value, the only way to obtain it is through mining (which requires special authorization on Signet) or through a faucet like this one. Faucets distribute small amounts of test coins so developers can immediately start building and testing without setting up mining infrastructure.

Frequently Asked Questions

Is Signet BTC real Bitcoin?

No. Signet BTC exists only on the Signet test network and has no monetary value. It is designed exclusively for testing and development purposes.

How much can I request?

You can request between 1,000 and 10,000 satoshis per request. There is a daily limit per IP address and per wallet address to ensure fair distribution.

Why is my transaction still "Pending"?

Transactions are batched together and broadcast at regular intervals to save on-chain resources. Check the "Next batch processing in" timer on the homepage to see when your transaction will be sent. After broadcast, it will confirm in the next Signet block (~10 minutes).

My address was rejected. Why?

This faucet only supports Signet addresses. Make sure your wallet is connected to the Signet network. Mainnet addresses (starting with bc1) and Testnet3 addresses are not accepted.

What is the difference between Signet and Testnet?

Testnet is an open network where anyone can mine blocks, leading to instability — blocks may come too fast or too slow, and spam can disrupt testing. Signet uses a permissioned model where blocks must be signed, providing consistent block times and a much more stable development environment.

Can I mine Signet BTC myself?

On the default Signet network, block production is controlled by authorized signers. You cannot mine blocks unless you run your own custom Signet with your own signing key. For most developers, using a faucet is the easiest way to get Signet coins.

The faucet says it is out of funds. What do I do?

The faucet balance depends on its on-chain wallet. If it runs low, please wait and try again later. You can also check the faucet balance displayed on the homepage. We work to keep it funded, but high demand can occasionally deplete it temporarily.

Can I return unused Signet BTC?

While there is no formal return process, you are welcome to send unused Signet BTC back to the faucet address to help other developers. The faucet address is displayed in the wallet section of this site.

Bitcoin Signet Glossary

Satoshi (sat)

The smallest unit of Bitcoin, equal to 0.00000001 BTC. Named after Bitcoin's pseudonymous creator, Satoshi Nakamoto.

Signet

A Bitcoin test network defined in BIP-325 that uses signed blocks for controlled, predictable testing environments.

Faucet

A service that distributes small amounts of cryptocurrency for free, typically used on test networks to help developers get started.

UTXO (Unspent Transaction Output)

The fundamental unit of Bitcoin's accounting model. Each UTXO represents an amount of Bitcoin that can be spent as an input in a future transaction.

SegWit (Segregated Witness)

A protocol upgrade that separates signature data from transaction data, reducing transaction size and enabling further improvements like the Lightning Network.

Taproot

A Bitcoin upgrade (activated November 2021) that improves privacy, efficiency, and smart contract capabilities through Schnorr signatures and Merkelized Abstract Syntax Trees (MAST).

Covenant

A proposed Bitcoin feature that would allow transaction outputs to restrict how they can be spent in future transactions, enabling use cases like vaults and congestion control.

Lightning Network

A layer-2 payment protocol built on top of Bitcoin that enables fast, low-cost transactions through a network of payment channels.
