finna - An Ethereum Blockchain Scratchpad

finna is still in early development, expect things to change

finna is a tool to quickly and easily read to and write smart contracts on the ethereum blockchain, and much more. finna runs in the browser and is powered by fif, a stack-based scripting language.

Here is an example of finna in action

;; finna - An Ethereum Blockchain Scratchpad;; Some user address that we're interested in
let some-address "0xad7ad87afdafdaf8d7afd8af7d";; Let's look at how much eth it has"some-address has " . (account/balance some-address)$ to-eth . " ETH" . cr
;; This uses etherscan to retrieve the contract ABI functions
let some-erc20-coin "0x32049328432098523059"
(contract/call some-erc20-coin :approve [some-address 10 to-wei]?)$
tx/wait-for ;; Wait for the returned transaction to complete;; Now that it's populated, this will transfer the given ERC20 coin;; from the provider (metamask, coinbase, etc) to the given address.
(contract/call some-erc20-coin :transfer-from [some-address 10 to-wei]?)$ tx/wait-for
;; The appropriate prompts will appear to carry out the transaction;; Assuming the account had no tokens previously, let's now confirm;; that the transfer completed successfully (there are better ways to;; do this, this is just a proof of concept)
(contract/call some-erc20-coin :get-balance [some-address])$ 10 to-wei >= if"Transfer Completed Successfully!" . cr
else
"Transfer Failed, or hasn't completed yet!" . cr
then
;; Write word functions
fn approve [address amount] &
(contract/call some-erc20-coin :approve [address amount] ?)$
endfn
(approve some-address 10 to-wei)$ tx/wait-for

finna is a tool to quickly and easily read to and write smart
contracts on the ethereum blockchain, and much more. finna runs in
the browser and is powered by fif, a stack-based scripting language.
Here is an example of finna in action
;; finna - An Ethereum Blockchain Scratchpad;; Some user address that we're interested in
let some-address "0xad7ad87afdafdaf8d7afd8af7d";; Let's look at how much eth it has"some-address has " . (account/balance some-address)$ to-eth . " ETH" . cr
;; This uses etherscan to retrieve the contract ABI functions
let some-erc20-coin "0x32049328432098523059"
(contract/call some-erc20-coin :approve [some-address 10 to-wei]?)$
tx/wait-for ;; Wait for the returned transaction to complete;; Now that it's populated, this will transfer the given ERC20 coin;; from the provider (metamask, coinbase, etc) to the given address.
(contract/call some-erc20-coin :transfer-from [some-address 10 to-wei]?)$ tx/wait-for
;; The appropriate prompts will appear to carry out the transaction;; Assuming the account had no tokens previously, let's now confirm;; that the transfer completed successfully (there are better ways to;; do this, this is just a proof of concept)
(contract/call some-erc20-coin :get-balance [some-address])$ 10 to-wei >= if"Transfer Completed Successfully!" . cr
else
"Transfer Failed, or hasn't completed yet!" . cr
then
;; Write word functions
fn approve [address amount] &
(contract/call some-erc20-coin :approve [address amount] ?)$
endfn
(approve some-address 10 to-wei)$ tx/wait-for
