Perform loads of swaps against the live 0x-api swap/quote endpoint.
Requires geth eth_call support (which Infura apparently has now).
Single source sims:
NODE_RPC=YOUR_GETH_RPC_URL yarn start {--url SWAP_QUOTE_URL} [--output SWAPS_OUTPUT_FILE.json] {--token SYMBOL} [--buys] [--sells] [--v0] [--jobs NUM_CONCURRENT_REQUESTS]Multi-source (A-B) sims:
NODE_RPC=YOUR_GETH_RPC_URL yarn start-ab {--url SWAP_QUOTE_URL} [--output SWAPS_OUTPUT_FILE.json] {--token SYMBOL} [--buys] [--sells] [--v0] [--jobs NUM_CONCURRENT_REQUESTS]| option | description |
|---|---|
--url -u URL |
The swap-quote API url. Can be repeated for ex: https://api.0x.org/swap/v0/quote. |
--output -o FILE |
JSON file to append sim data to. The python analytics tools can parse this file. |
--token -t TOKEN |
Tokens to include in the simulations. Can be repeated. Defaults are WETH, DAI, USDC. |
--jobs -j N |
Number of concurrent requests to make. Default is 1, which is very slow. |
--buys |
Whether to only do buy swaps. Default is both. |
--sells |
Whether to only do sells swaps. Default is both. |
--v0 |
Whether to run in v0 (non-Exchange Proxy) compat mode. This will prevent swaps to ETH. |
There are a bunch of analysis scripts in the /py folder. Just run them directly, passing the swap output file in.
The first time simbot is run (through start or start-ab) a config.json file will be created in the root. You can configure certain addresses and contract overrides from this file.
