Description

Personality Swap transforms personality tests into digital identities on-chain.
Instead of static results that get forgotten, your MBTI type becomes a composable ERC-721 token that you can save, share, and swap.

Problem

In the fast-moving world of crypto, social apps, and trends, people often make rushed decisions out of fear of missing out (FOMO).
This leads to impulsive trades, wasted time, and regret over choices that weren’t aligned with their real personality or goals.
There’s no fun, interactive way for people to explore their decision-making style while learning to resist FOMO.

Solution

Personality Swap turns decision-making into a self-aware, gamified experience.
Instead of following hype, users can:

• Discover their MBTI archetype and how it relates to risk behavior
• Save their personality onchain as an NFT — a permanent reminder of who they are
• Share their identity socially in a transparent way, instead of chasing trends
• Use personality insights as a tool to slow down, reflect, and avoid FOMO

This creates a playful but powerful method for making choices safer, more intentional, and less reactive.

Challenges we ran into

Challenges I Ran Into

One major challenge I faced was trying to integrate with Coinbase OnchainKit while developing in Indonesia.
Since Coinbase services are blocked in this region, direct access to APIs and wallet connections often failed.

This limitation made testing and debugging extremely difficult, as I couldn’t easily authenticate or connect a wallet the way users in other regions could.

To work around this, I had to:

• Use VPNs and network tunneling to simulate access from supported regions
• Rely heavily on testnets like Base Sepolia to validate contracts and flows
• Mock certain Coinbase responses locally so I could keep building without waiting on full connectivity

This taught me how to design resilient workflows and test environments even when infrastructure access is limited.
