Wasm Smart Contracts Bounty #19
Big Spender


We are re-submitting this proposal. The bounty itself is already proposed on-chain and approved once. However, the approval of the bounty has to be initiated again, even though the community has already approved it via previous governance. This means we would still have to ensure that the new referendum gets sufficient approval and support to enact and bounty to get funding.

Here is the referendum approved but failed to execute.

Here is the error message we got on-chain.

Here is the previous community discussion on Polkassembly.


This bounty aims to nurture and develop WebAssembly smart contracts on parachains. As Gavin mentioned in this CoinDesk article, WebAssembly is the future of smart contracts. However, even in the Polkadot ecosystem, EVM smart contract is the go-to-market solution now simply because lack of ecosystem toolings and dApps new developers can refer to. To bootstrap the Wasm dApps in the ecosystem, we will fund canary dApps and toolings through this bounty.

Context of This Bounty

Please see this post first. Currently, based on the data, smart contract Parachains are leading the Polkadot ecosystem in terms of market adoption. More projects are deploying dApps on Polkadot Parachains than making Parachains today and this trend will likely continue due to the high resource requirement to deploy a chain. The core problem is that the Polkadot ecosystem only supports EVM at the time of writing this and we are reproducing something which other L1s/L2s can do. One of Polkadot’s main differentiators and default environments is Wasm. In this bounty, we would like to push Wasm smart contracts adoption. The scope is as follows:

  • Create easily accessible and audited ink!/ask! smart contract showcases
  • Create ink!ubator - an incubation program to support community projects built with ink! and parachains that want to expose select APIs through contracts-pallet “chain extensions”. We will also help facilitate a smart contract auditing market.
  • Develop a React hooks library “useInk” - the missing front-end library for Dapps on Polkadot.
