Each GromaCoin, or GRO, represents an equity stake in the trust, which owns and operates a portfolio of multifamily residential properties, according to Groma.

The integration changes the transaction channel, not the requirement for investor approval. Groma’s investment site labels GromaCoin purchases “available for accredited investors only.” Its whitepaper says wallets must be allowlisted after identity and anti-money-laundering checks.
Issuer Controls Stay Intact
Uniswap introduced the Permissioned Pools standard in July. Its technical documentation says the hook—a smart-contract extension that adds rules to a pool—checks permissions for each swap and before a liquidity position is created. Trading and liquidity provision have separate permission flags.
The issuer implements and deploys the contract that checks wallet eligibility. The issuer-controlled adapter can change that checker, approve or revoke the contracts used to access the pool, and pause swapping. These restrictions operate through smart contracts rather than just a website’s access controls.
The design also keeps the underlying restricted token out of Uniswap v4’s shared pool-management contract. An approved adapter holds the asset while the pool trades a virtual representation; routing contracts handle conversion automatically. Uniswap’s documentation says this avoids creating freely tradable claims that could bypass the token’s ownership restrictions.
Liquidity-position NFTs are non-transferable, preventing an approved investor from handing a position to an unapproved wallet. The broader Uniswap protocol remains permissionless, but participation in these pools is restricted to approved holders.
