Computer

The Computer class has the methods listed below.

Basic

You can build almost all smart contracts with these.

Method	Description
constructor	Creates an instance of class Computer
new	Creates a smart object from a smart contract
query	Finds the latest revisions of smart object
sync	Computes the state of a smart object from a given revision

Modules

Deploy JavaScript modules (preferably via taproot) to avoid redundant on-chain storage for smart contracts, keep using expressions tiny, and minimize on-chain technical dust / hygiene dust costs. See Fees for details and best practices.

Method	Description
deploy	Deploys a JavaScript module on the blockchain
load	Loads a JavaScript module from the blockchain

Advanced

For advanced applications that require control over how the transaction is signed, the UTXOs to be spent, custom scripts, or collaborative transaction building.

Method	Description
encode	Encodes a JavaScript expression into a Bitcoin transaction
encodeNew	Encodes a constructor call into a Bitcoin transaction
encodeCall	Encodes a function call into a Bitcoin transaction
decode	Parses a Bitcoin transaction and returns JavaScript expression
faucet	Fund a computer object on Regtest

History

Access historical versions of on-chain objects.

Method	Description
first	Return the first revision
prev	Return the previous revision
next	Return the next revision
latest	Return the latest revision

Wallet

Access the client side wallet.

Method	Description
sign	Signs a Bitcoin transaction
broadcast	Broadcasts a Bitcoin transaction
send	Sends satoshis to an address
rpc	Access Bitcoin's RPC interface
getAddress	Returns the Bitcoin address of the computer wallet
getBalance	Confirmed, unconfirmed and total balance in sats
getChain	Returns the blockchain
getNetwork	Returns the network
getMnemonic	Returns a BIP39 mnemonic sentence
getPassphrase	Returns the passphrase
getPrivateKey	Returns the private key
getPublicKey	Returns the public key
