This contract has been designed to put key value pairs into storage with replace and clear key/value pairs with clean from an account's storage.
Deploy this contract into the account that already has another contract deployed to it.
This contract on call clean will remove any items of the state specified (keys should be specified in base64). When compiled with replace feature, replace method can be called with an array of key/value tuple pairs to insert into state.
JSON format for clean:
{"keys":["<base64 encoded key byte string>", "...", "..."]}JSON format for replace:
{"entries":[["<base64 key byte string>", "<base64 value byte string>"], ["...", "..."]]}Usage example to put and remove only the "STATE" item using near-cli:
# Build the contracts will all feature combinations
./build.sh
# Deploy built code on chain
near-cli add contract-code network testnet account nesdie.testnet contract-file ./res/state_manipulation.wasm no-initialize sign-with-keychain
# Add state item for "STATE" key
near-cli execute change-method network testnet contract nesdie.testnet call replace '{"entries":[["U1RBVEU=", "dGVzdA=="]]}' --prepaid-gas '100.000 TeraGas' --attached-deposit '0 NEAR' signer nesdie.testnet sign-with-keychain
# View Added state item
near-cli view contract-state network testnet account nesdie.testnet at-final-block
# Clear added state item
near-cli execute change-method network testnet contract nesdie.testnet call clean '{"keys":["U1RBVEU="]}' --prepaid-gas '100.000 TeraGas' --attached-deposit '0 NEAR' signer nesdie.testnet sign-with-keychain
# View that item was removed
near-cli view contract-state network testnet account nesdie.testnet at-final-blockclean: Enables clean method to remove keys
replace: Enables replace method to add key/value pairs to storage
