Feature/bandwidth token (#832)
* Remove check for bandwidth for incoming packets We should only accunt for packets that the client inputs to the mixnet * Introduce BandwidthController for both types of bandwidth creds * Add some non-coconut token bandwidth handling * Use thiserror for gateway-client lib * Add error handling * Unable to build for wasm for now * Fix wasm strange error * Disable non-coconut credentials for wasm client * Check for status and throw the error up * Send encrypted token cred from client * Gateway receive message and signature validation * Put the correct amount of tokens that were burned * [ci skip] Generate TS types * Eth endpoint and secret key as config parameters * Add eth_endpoint config argument for gateway * Update test as well * Separate panicable code from the safe one * Move some bandwidth controller panics up the call stack * Save contract corresponding to the eth endpoint * Fix template * Pass the web3 interface as well * Made event reads possible in gateway * Add checks for event data * Cosmos contract for double spending prevention * Add workflow for the new contract * Add validator rest URL to config * Rename eth_events to erc20_bridge * Pass cosmos mnemonic as well, and put the nymd client in ERC20Bridge * Call cosmos contract for final verification * Ask for config parameters in cli * Fix various stuff * Increase timeout to allow gateway to check the two chains * Put some logs for the new flow * Set consumed bandwidth invariantly of coconut feature * Fix clippy error * Add non-coconut checks * Use 2018 rust instead of 2021 * More verbose nymd error * Explicitly specify TOKENS_TO_BURN constant * Put eth burn function in a constant * Replace to_vec & append with iter & chain * Test for (de)serialization of TokenCredential * Minor rename * Separate credential creation from bandwidth claiming * Switch from panics to errors when claiming coconut bandwidth * Another append changed to chain * Update QA cosmos contract address * Simplify build/test/clippy separation on coconut feature * Fix bad features arg positioning * Use the start_after in cosmos contract query * Set a limit in line with a range on cosmos queries * Added unit tests for new cosmos contract * Fix bandwidth_remaining comparation * Get remaining bandwidth from gateway * Add contract build flag * Add a useful info log * Use a more robust eth depth for release builds * Include recipt logs in error message * Fix clippy for tests * Use Arc instead of clone * Rename as_bytes to to_bytes * Make signature verification in contract more verbose * Missed rename of paging constant * Fix gateway start with coconut enabled * Rename function to claim_token * Simplify nymd client setup * Check with block buffer on gateway as well * Update comment of double spending protection * Correct contract address * Backup the keypairs used for buying tokens, in case of error cases * Don't take any chances with the gateway timeout * [ci skip] Generate TS types * Updated cosmos contract to latest QA address * Add cli options for eth * Update network monitor timeout value as well Co-authored-by: neacsu <neacsu@users.noreply.github.com> |
