Funding a Portfolio Wallet
Funding and allocation are separate stages. An external transfer first becomes cash in the Portfolio Wallet. A later Ground-managed rebalance deploys that cash according to the wallet’s strategy. Funds are allocated within compatible allocation groups. The selected group determines which positions and withdrawal destinations those funds can support. Supported Chains describes stablecoin coverage and network movement.Signing Portfolio Wallet actions
Ground uses Turnkey to sign Portfolio Wallet transactions according to the wallet’s configured policies. Ground then broadcasts the signed transaction on the selected network. Yield-source actions execute through Ground routing contracts or programs, while payouts transfer stablecoins to the withdrawal destination. Some actions require approval from the organization’s configured signer before Turnkey releases the signature. See Transaction Approvals for the approval API and verification flow.Direct protocol positions
A direct protocol allocation supplies stablecoins to the selected protocol and leaves the resulting position token or vault share in the Portfolio Wallet. Redemption converts that position back into the source’s stablecoin.
An exit follows the corresponding protocol’s redeem path. Some direct protocols settle in one transaction; others require additional waiting or settlement steps before stablecoin is available for payout.
Ground RWA Vault positions
Ground RWA Vault sources use dedicated vault contracts on EVM or vault programs on Solana. The Portfolio Wallet submits the source’s action through the corresponding Ground router, then holds a wallet-specific, non-transferable Ground receipt rather than an underlying provider instrument directly. Use the live catalog for available sources and their networks. Depending on the product and available liquidity, a Ground RWA Vault deposit may settle immediately or use the following asynchronous deposit lifecycle: Ground RWA Vault exits use the corresponding redemption lifecycle: the wallet requests redemption, provider settlement and vault processing complete, the wallet claims stablecoin, and Ground sends the payout to the withdrawal destination. Some vaults can settle through available onchain liquidity; otherwise the asynchronous path applies. Each withdrawal payout leg settles and pays out independently.Processing policies in the Yield Sources catalog describe operational estimates. Actual completion depends on external fulfillment and vault processing. Because payout legs may settle at different times, each requires separate approval when signing keys are configured in the developer portal. See Transaction Approvals for details.
