Welcome to the Blockchain
Composable Blockchain Solutions
With Komodo, you can deploy a composable Smart Chain in minutes with seamless interoperability, atomic swaps, and Turing-complete business logic.
Komodo’s Antara Framework is an adaptable framework for simple, end-to-end blockchain development. Antara makes it easier than ever before to launch a chain, activate modules, and start building blockchain-based applications.
Smart Chains are compatible with Komodo’s cross-chain atomic swap technology. Next-generation wallets, such as Komodo’s AtomicDEX application, allow users to trade assets wallet-to-wallet without any middlemen or third-parties.
- This tool is a fork of OutCast3k/coinbin modified to use with Komodo (KMD) and kmdexplorer.io API.
- It is still experimental and a work-in-progress. Use at your own risk without warranty of any kind!

New Address create a new address
Any keys used you will need to manually store safely as they will be needed later to redeem the bitcoins.
Address Options
You can use the advanced options below to generate different kind of keys and addresses.
New SegWit Address Smaller & Faster Transactions
Any keys used you will need to manually store safely as they will be needed later to redeem the bitcoins.
Address Options
You can use the advanced options below to generate different kind of keys and addresses.
New Multisig Address Secure multisig address
Public keys can be generated in your browser or from your bitcoin client.
Enter the public keys of all the participants, to create a multi signature address. Maximum of 15 allowed. Compressed and uncompressed public keys are accepted.
Enter the amount of signatures required to release the coins
New Time Locked Address Coins can be released only after a certain date
Use OP_CHECKLOCKTIMEVERIFY (OP_HODL) to create a time locked address where the funds are unspendable until a set date and time has passed.
Public keys can be generated in your browser or from your bitcoin client.
Enter the public key that will be able to unlock the funds after the a certain date.
Enter the or required to release the coins:
New HD Address making bip32 even easier

Address, WIF key or Redeem Script:Bitcoin Fee Calculator
This page will give you a guide on the lowest fee to use to get your transaction included within the next few blocks. It works by predicting the size of a transaction and comparing it to another transaction in a recent block to determine an appropriate fee.
Recommended Fee: 0.00000000 KMD

About open source komodo tool
- This tool and site is a fork of OutCast3k/coinbin project with added KMD (Komodo) support.
- Added Insight based explorer API integration for load UTXOs for create and sign transactions.
- Signing transactions don't work offline! Bcz since KMD had sapling activated to sign arbitrary raw tx app need to know not only txid and vout num of each vin, but also exact amount and few other info, which can be obtained from blockchain. Online connection to explorer API used only during signing txes to obtain vins info, all other features can be used offline. For more information about Transaction Signature Verification for Sapling plz refer to ZIP-243 document.
- KomodoPlatform and Komodo Team are not related to this wallet. It's 3rd party developement.
- Sources of this project are available on GitHub in komodo branch.
- Please, remember that some things can be buggy, so don't use this tool with addresses having more coins than you can allow yourself to lose!

This page uses javascript to generate your addresses and sign your transactions within your browser, this means we never receive your private keys, this can be independently verified by reviewing the source code on github.
