Cipher Examples

This repo contains a collection of example contracts that run on Cipher, the confidential Oasis Wasm ParaTime.

The Examples

• vigil - A dead-person's switch that confidentially stores secrets until a (refreshable) set time.

How to use

1. Grab the Oasis CLI. It can be used to upload, instantiate, and call contracts on Cipher.
2. Compile a contract using cargo build --release --target wasm32-unknown-unknown
3. Optionally, optimize the contract using wasm-opt

   TARGET_DIR="target/wasm32-unknown-unknown/release"
   wasm-opt "${TARGET_DIR}/<contract>.wasm" -o "${TARGET_DIR}/<contract>.opt.wasm" -O3 -c
   

4. Upload the contract: oasis contracts upload "${TARGET_DIR}/<contract>[.opt].wasm"
5. Instantiate the contract: oasis contracts instantiate <the-instance-id> <yaml-args>
6. Call the contract: oasis contract call <the-instance-id> <yaml-args>
