Different set of tools with the Polkadot API.
Use PNPM to avoid dependency conflicts
Use at your own risk!
Install packages:
pnpm install
Then, run script with node or python (python3) depending on the file
calculateAddressStorageKey calculates the storage key for an EVM address
calculateDerivedAddress calculates the derivative address of a given index
calculateMultisigAddess calculates a multisig address based on an array of address and a threshold, for example:
ts-node calculateMultisigAddress.ts --a '["14gZZ9xc52TKDJA6LmzX7iVBcdPeBNX6B3NkGubKd6pLTcSe","1333RgL47QYYkmJk1BHzfEF4hRE7Bd2Yf8P2HdV8Cn3p9hVh"]' --t 2
checkBlockFinality prints the latest finalized block in the provided chain
checkTxFinality checks if a given Tx Hash has been finalized (both for node or python)
createSR25519Acc script to create a number of SR25519 with a given prefix, they are saved into a JSON file
encodeDecodeAddress simple snippet to show encode and decode functionity for substrate accounts
estiamteTxFee estimates the transaction fee for a given call
getAccFromJSON prints the private key of a JSON file (DO NOT SHARE YOUR PRIVATE KEY)
getAddressFromMnemonic derives the Ethereum address (for a given index) from a mnemonic using the m/44/60/0/0/0 derivation path and logs the associated private key. Also derives the Substrate generic address with the //hard/soft derivation path
getBalanceEvents fetches all balance transfer events via the Substrate API
getBlock gets a substrate block with a given hash
getCrowdloanContAddress. script retrieve and save in a JSON file all Crowdloan rewards information for a given network
getEthAddressFromPrivKey shows the Ethereum address associated to a private key
getStakingAddress fetches all the addresses that are staking and their total in either moonbeam or moonriver (input with yargs like node getStakingAddress.js --network moonbeam)
getStakingData gets staking data from all collators
nestAsDerivatives nests as derivative calls to as many levels as desired and provided the encoded call data
sendSubstrateTx script to send a simple tx using the Substrate API, only works with SR25519 accounts (not Moonriver!). You need to provide the origin account mnemonic. Not safe for production!
setDummyCode calculates the encoded call data to set the dummy code for the provided precompiles
verifyMessage verifys a signed message by providing the signers public Address, the message and the signed message
PALTxGenerator a specific script that helps generating Polkadot Assurance Legion Multisig transactions
