Multi-chain on-chain eligibility

CollabOS separates wallet identity from raffle submission.

Signed wallets

• prove wallet control with a one-time message signature
• can be used to sign in after they are linked to a CollabOS account
• are used for native raffle blockchain holding checks
• never become the submitted mint wallet automatically

Mint wallets

• are destination/submission addresses saved for raffle entries
• can have primary and per-community defaults
• do not prove ownership simply because an address was saved

Native holdings verification in this release supports EVM networks through configured JSON-RPC endpoints and Solana through a configured Solana RPC endpoint. The EVM adapter covers Ethereum-style networks such as Ethereum, Base, Arbitrum, Polygon, ApeChain, Abstract, Monad, and Optimism when the corresponding RPC is configured.

Token/NFT requirements can contain multiple contract addresses. The contracts use ANY/OR semantics: satisfying any listed contract passes the requirement. A holding multiplier can use the qualifying holding count to increase entry weight.

Bitcoin, Stacks, Sui, and TON can still be used as mint-wallet labels/addresses, but their automatic signed-wallet proof and holdings adapters are not enabled by this patch.
