v0.6

Wave Protocol v0.6 beta

New features

• Updated deployment scripts to clone canonical Nouns state-write transactions from mainnet to testnet
• Deployed a new renderer pointing to our testnet mock Nouns infra contracts
• Upgraded to new IdeaTokenHub implementation with URI function now delivering base64-encoded json containing relevant "name", "description ", "external_url" and "image" metadata
• Documented new deployment addresses for v0.6
• Test cases for URI changes

v0.5

Wave Protocol v0.5 beta

New features

• Upgraded to new IdeaTokenHub implementation providing new functions targeting dynamic rendering of SVG metadata. Offchain components can now query the standardized ERC1155::uri() function to render token metadata via onchain SVG
• Deployed and integrated the Wave canonical font as well as a testnet version of 0xBeans/FontRegistry to which the Polymath-Text font was added in order for the Renderer to fetch by routing through the FontRegistry
• Added functions for the IdeaTokenHub to handle reading and writing on the Renderer- uri() and owner-gated functions like setRenderer() and setStaticURI()
• Updated deployment scripts to reflect new SVG metadata contracts
• Temporary IFontRegistry interface while waiting for the 0xBeans/FontRegistry to merge outstanding PR

Contract deployments to Base Sepolia are as follows:

v0.4

Wave Protocol v0.4 beta

New features

• Upgraded to new IdeaTokenHub implementation providing new functions targeting improved custom dynamic URI logic as well as offchain devX: getWaveInfo(), getCurrentWaveInfo(), and getParentWaveId()
• Refactored IdeaTokenHub contract state management of Wave information to enable historical queries of previous Waves
• Updated and renamed SponsorIdeaevent to WaveFinalized which now provides information about the concluding Wave
• Abstracted logic within IdeaTokenHub::finalizeWave() into internal functions named _processWinningIdeas() and _updateWaveState() to preemptively address tech debt and prevent "Stack too deep" errors from arising in the future

Contract deployments to Base Sepolia are as follows:

Name	Contract Details	Contract Address
