The Future of Custody: Shared, Not Surrendered

Users face an impossible choice: self-custody (risky, complex), centralized custody (counterparty risk), or institutional custody (expensive, illiquid). This fragmentation creates systemic risk and stifles innovation.

• ~$40B+ lost to exchange hacks and fraud.
• Zero native yield on self-custodied assets.
• No programmability across isolated silos.

Leverage cryptoeconomic security from base layers (like Ethereum, Solana) to secure assets across applications. Think EigenLayer for restaking, Babylon for Bitcoin staking, and Celestia for modular data availability.

• Reuse $100B+ in staked capital.
• Slashable security for any application.
• Unlock new cryptoeconomic primitives like pooled sequencing.

Users specify what they want, not how to do it. Protocols like UniswapX, CowSwap, and Across solve for best execution, while ERC-4337 account abstraction handles gas and key management.

• ~30% better prices via order flow auctions.
• Gasless transactions sponsored by applications.
• Social recovery replaces seed phrase panic.

Assets move seamlessly across chains via verified bridges (like LayerZero, Axelar, Wormhole) and universal states like Polygon AggLayer or Cosmos IBC. Custody becomes a portable property, not a chain-specific lock-in.

• ~2s finality for cross-chain messages.
• Unified liquidity across $1T+ ecosystem.
• Verifiable security with light clients.

FTX and Celsius proved that surrendering private keys creates a single point of failure. This model is antithetical to crypto's core value proposition of self-sovereignty.

• $10B+ in user funds lost to custodian failures.
• Creates regulatory attack vectors and compliance bottlenecks.
• Limits composability and programmability of assets.

Entities like Fireblocks and Coinbase WaaS use MPC to split a private key into shards, distributing trust. No single party can move funds unilaterally.

• Enforces M-of-N approval policies for transactions.
• Reduces key theft surface; a single compromised device is insufficient.
• Provides enterprise-grade security with ~99.99% uptime and audit trails.

Protocols like Safe{Wallet} and Biconomy turn wallets into smart contracts. Custody logic is programmable, enabling social recovery, batched transactions, and gas sponsorship.

• Shifts risk from a single key to a verifiable smart contract.
• Enables permissioned spend limits and time-locks.
• ~10M+ Safe smart accounts created, representing a foundational standard.

Architectures like UniswapX, CowSwap, and Across separate custody from execution. Users sign intents (what they want), not transactions (how to do it). Solvers compete to fulfill them.

• User retains asset custody until the moment of settlement.
• Eliminates MEV extraction and improves price execution.
• ~$20B+ in intent-based volume processed to date.

Frameworks like Zodiac for Safe and Lit Protocol allow developers to attach custom security logic to shared custody setups. This creates dynamic, context-aware custody rules.

• Enables DAO governance over treasury movements.
• Allows cross-chain conditional logic (e.g., release funds if event X occurs on Chain Y).
• Moves security from static configuration to active, verifiable policy.

Protocols like EigenLayer and restaking primitives are building shared security models where custody of staked assets is distributed across a decentralized operator set. This creates cryptoeconomic security without centralized custodians.

• $15B+ TVL in restaking, demonstrating demand for shared security.
• Turns passive assets into active, yield-generating collateral.
• Foundations for interoperable security layers across the modular stack.

Guardians are the new private keys. Attackers now target human relationships, not cryptographic entropy.\n- Phishing targets guardians via email, SMS, or fake support calls.\n- Sybil attacks can infiltrate guardian sets over time.\n- Legal coercion (writs, subpoenas) can compel key disclosure from trusted entities.

Recovery assumes guardians are reachable, willing, and technically capable. This creates systemic risk.\n- Geographic dispersion leads to latency and timezone failures.\n- Key loss by guardians themselves (dead man's switch).\n- Protocol upgrades can strand guardians on incompatible software versions, breaking recovery.

To mitigate social risk, users default to institutional guardians (Coinbase, Wallet-as-a-Service), recreating custodial honeypots.\n- Regulatory capture: Institutions must comply with KYC/AML, negating privacy.\n- Single point of failure: The guardian service becomes a target for hackers and nation-states.\n- Protocol dependency: Relies on the continued operation of entities like Safe, Coinbase, Fireblocks.

MPC and threshold schemes are vulnerable to straightforward bribery if the cost to corrupt a quorum is less than the wallet's value.\n- Transparent on-chain funds make target valuation trivial.\n- Collusion markets could emerge to efficiently bribe guardian subsets.\n- This turns security into a pure game-theoretic problem, not a cryptographic one.

Social recovery fragments identity across devices, authenticators, and biometrics, increasing the attack surface.\n- Device compromise (malware on a guardian's phone).\n- Biometric spoofing (deepfakes for voice/facial auth).\n- Cloud backup breaches (iCloud, Google Drive storing encrypted shards).

For DAO treasuries or smart contract wallets, social recovery modules are governed by tokens. This creates a meta-attack.\n- Token voting attacks (flash loan, vote buying) can change guardian sets.\n- Timelock bypass through social consensus.\n- Upgrade hijacking to a malicious implementation, as seen in Nomad, Polygon bridge hacks.
