Sequentia

Downloads

Software for the Sequentia testnet, a proof-of-stake sidechain where every block commits to a Bitcoin testnet4 header, addresses are transparent by default, and fees are payable in any accepted asset.

Sequentia Core

version 25.2.2

The full node and its desktop wallet. It validates the chain for itself rather than trusting a server, and it is the software a block producer runs.

Wallet: send, receive and issue assets; tSEQ is one asset among them.
Staking tab: committee schedule, stake weights and staking-output tools.
Anchor watching: follows Bitcoin testnet4 and reorgs when it does.
Any-asset fees: pay a fee in whichever asset a producer accepts.

Install · Linux: extract the tarball and run bin/sequentia-qt. Windows: run the installer, then launch Sequentia Core. It connects to the testnet on its own.

Fulmen ⚡

version 0.2.0 testnet preview

A desktop wallet for SeqLN, the Sequentia Lightning Network, with a full SeqLN node bundled in. Point it at a Sequentia node's RPC on first run and it starts Lightning against it; add a Bitcoin node and it runs Lightning on testnet4 as well.

Asset channels: Lightning channels denominated in issued assets, not only BTC.
Any-asset payments: pay asset= chooses what a payment moves.
Per-asset balances: channel liquidity broken out by asset.
Windows: the node runs inside WSL2, installed on demand.

Install · Linux: make the .AppImage executable and run it. Windows: run the installer (one click, for your user account), or take the portable zip and run Fulmen.exe.

Seqognito 🕶

version 0.1.0 testnet preview

A wallet for mixing. Your coins go into one transaction together with other people's and come out somewhere nobody can follow — and because Sequentia has confidential transactions, the amounts are hidden too: every output of the round, your change included, is a commitment rather than a number. It holds Bitcoin and Sequentia assets, receives and sends, and deliberately does nothing else.

Everything over Tor: the window has no network of its own, and the wallet will not send anything without a SOCKS proxy.
Two circuits, not one: your coins and your mixed addresses are registered over separate Tor circuits, so the coordinator sees two strangers.
Any node you like: point it at your own Sequentia and Bitcoin endpoints, .onion included.
Bitcoin too: parent-chain BTC is bridged in, mixed, and sent back out to an address you have never used.

Install · You need Tor running — a system tor daemon (port 9050) or Tor Browser (9150). Linux: make the .AppImage executable and run it. Windows: run the installer, or take the portable zip. On first start it asks which nodes to use, and encrypts your recovery phrase with a passphrase.

What it does and does not hide · The chain learns nothing about the amounts. The coordinator cannot link your coins to your mixed outputs, though it does see your amounts and your change. Your anonymity set is the round you were in — a round with two people in it hides you among two.

Ambra for Android

version 0.17.5 testnet preview

A non-custodial dual-chain mobile wallet: one recovery phrase for Bitcoin testnet4 and Sequentia, sharing one tb1 address, so BTC is a first-class asset rather than an add-on. Built on SWK, the Sequentia Wallet Kit.

Issue assets: create and reissue your own, including OpenAMP restricted assets.
SeqDEX terminal: market and limit orders, same-chain or cross-chain, on-chain or over Lightning.

Install · Allow “install unknown apps” for your browser, then open the .apk. There is no iOS build.

Pignus CLI

version 0.3.0 testnet preview

Collateralised lending from the command line, against your own node. Everything the lending site does — propose a loan, publish a funded offer, borrow, repay, liquidate — plus the one check the whole thing rests on: rebuild a vault’s address from the terms you agreed and refuse to sign if it differs.

Verify before you sign: pignus-cli verify rebuilds the vault address from your terms and refuses if one atom of the debt, the strike or the oracle differs.
Run your own oracle: sign prices for your own markets and publish every attestation, so a liquidation can always be checked afterwards.
Run your own liquidator: liquidation is a permissionless race and anyone may enter it. Nothing about Pignus depends on the operator’s bot.

Pure Python, no build step. It needs a Sequentia source checkout, because the loan covenant lives in the node repository and Pignus imports the proven builder rather than carrying a copy of it: set SEQUENTIA_SRC and run tests/cli_drill.sh to check the wiring. sha256 dd8b849881c8b8d7c983b666bdd269fde3d04b6557d73dfb62688766189e22cc

Ambra for Chromium

version 0.5.28 testnet preview

The same dual-chain wallet as a browser extension for Chrome and other Chromium browsers, plus a window.sequentia API that lets a website ask the wallet to connect, sign and pay.
